Lever: A bar that pivots around a fixed point, or fulcrum, to amplify or change the direction of applied forces.
Pulley: A grooved wheel with a rope or cable passing over it, used to change the direction of an applied force.
Inclined Plane: A flat surface that is angled, used to reduce the amount of force needed to lift an object.
Wedge: A triangular shape with one sloping side, used to split or lift objects by applying force at the sloping angle.
Screw: A spiral groove that helps convert rotational motion into linear motion.
Wheel and Axle: A cylinder that rotates around a central point (the axle), used to reduce the amount of force needed to move an object.
Why must the lamina swing freely when determining the centre of gravity?
By allowing the lamina to swing freely, the object's true weight distribution and the center of gravity can be observed and determined with greater accuracy.
The lamina (such as a flat plate or sheet) must be able to swing freely when determining the center of gravity (also known as the center of mass) for a few reasons:
First, the center of gravity is the point at which the weight of an object is evenly distributed, and the object will be balanced when suspended from that point. In order to determine the center of gravity, the object must be allowed to rotate or move freely, so that its weight distribution can be observed.
Second, if the lamina is not able to swing freely, it would be affected by external forces such as friction or air resistance, which could influence the object's weight distribution and give an inaccurate location of the center of gravity.
Third, if the lamina is not able to swing freely, it would be difficult to observe the object's movement, and therefore it would be difficult to determine the center of gravity.

removing heat will lower the ___, causing the particles of the reactants to slow down, resulting in less frequent collisons
Removing heat will lower the temperature, causing the particles of the reactants to slow down, resulting in less frequent collisions.
Give a short note on temperature?The temperature of a system is a measure of the average kinetic energy of the particles that make up the system. As the temperature decreases, the kinetic energy of the particles decreases, and their movement slows down. In a chemical reaction, the reactant particles collide with each other in order to react. The more frequently and forcefully they collide, the more likely they are to react. So if the temperature is lowered, the rate of the chemical reaction will decrease because there will be fewer successful collisions between the reactant particles.

a ball is thrown and follows the parabolic path shown. point q is the highest point on the path and points p and r are the same height above the ground.
Because of freefall, The only acceleration working on the ball is gravity in the parabolic path shown. Thus, Option C is correct.
What is parabolic path?Parabolic motion is a type of projectile motion in which an object is thrown or projected into the air and follows a curved path due to the influence of gravity.
In the case of the diagram, the ball is thrown upwards and follows a parabolic path. Point Q marks the highest point on the path and points P and R are the same height above the ground. This can be explained by the fact that the initial velocity of the ball is insufficient to reach a higher point than Q, so after reaching Q the ball begins to fall back to the ground, travelling the same distance at P and R before it reaches the ground.
The parabolic motion of the ball can be described by the equation s = u ×t + 0.5 × a × t2, where s is the displacement of the ball, u is the initial velocity, t is the time elapsed, and a is the acceleration due to gravity. This equation can also be used to calculate the maximum height that the ball will reach, in this case point Q.
The parabolic motion of the ball can be used to explain the physics behind a variety of scenarios, such as how a ball thrown into the air will move, how a skydiver will fall, and even how a spacecraft can be propelled into outer space. It is a fundamental concept in physics and understanding it can help to explain many of the phenomena we observe in our everyday lives.

What happens if you move a magnet back and forth inside a coil of wire?
When we move the magnet back and forth inside the coil of the wire, it will produce a voltage.
When a magnet moves into a coil of wire, the magnetic field and flux through the coil change, creating a voltage in the coil according to Faraday's Law. In the example shown below, as the magnet moves into the coil, the galvanometer deflects to the left in response to the increasing magnetic field. When a magnet or coil repeats the reciprocating motion, alternating current is generated. Generators and transformers use electromagnetic induction to generate electricity and change the voltage of current. When the magnet is moved towards the coil, a current is induced in the coil due to the phenomenon of electromagnetic induction. The relative motion between the magnet and coil induces an electromotive force (EMF), which induces a current in the coil.

Inertia is directly proportional to the mass of an object, so the more massive an object is, the greater its inertia.
What, in layman's terms, is inertia?A body's inherent property of inertia makes it resistant to any force that would alter its motion. Acceleration could be caused by opposing forces acting on a still and moving body.
What exactly is motion inertia?Motion inertia: The fundamental property that a body has to resist any change in its motion is called inertia of motion. In other words, inertia of motion is when the body doesn't want to change its motion but wants to stay in its current state.
What motion law is inertia?Inertia refers to a body's ability to remain stationary or in motion at a constant speed. The "law of inertia" is a common name for Newton's first law.
Question incomplete:The velocities and masses of four objects are shown. Which object has the greatest inertia?

The proper way to fire a shotgun is raise the shotgun to the cheek and back to the shoulder, on the side of the dominant eye; and point at the target.
Shotguns are generally fired at a target and not aimed like rifles. They discharge shells or loads that may include a propellant wadding followed by a slug, shot, or other type of specialized projectile.
It is possible to fire a conventional bullet from a shotgun, which typically fires a plastic "shell" filled with numerous projectiles called "shot." This is accomplished using a device known as a "sabot" .
This is a single bullet that is loaded into a shotgun shell and is protected by a plastic or foam cylinder. After being fired, the plastic or foam cylinders separate along pre-scored lines and fall away as the single bullet continues on its course.

tai ran from his home to a position 300 m south of his home in 100 seconds what was his velocity
Velocity = distance / time = 300m / 100s
= 3 m/s
What is Velocity?Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by a specific unit of time (for example, 60 km/h northbound).
A physical vector quantity called velocity must have both a magnitude and a direction in order to be defined.
Speed is the scalar absolute value (magnitude) of velocity; it is a coherent derived unit whose quantity is measured in metres per second (m/s or m/s1) in the SI (metric system).
Therefore, Velocity = distance / time = 300m / 100s
= 3 m/s

the specialty of an athlete on the women's track team is the pole vault. she has a mass of 60 kg and her approach speed is 8.7 m/s. when she is directly above the bar, her speed is 1.4 m/s. neglecting air resistance and any energy absorbed by the pole, determine the amount(in m) she has raised herself as she crosses the bar.
The height(in m) she has raised herself as she crosses the bar with initial speed of 8.7m/s is found to be 3.76m
What does energy conservation mean?A fundamental law of physics and chemistry asserts that despite internal changes, the overall energy of an isolated system remains unchanged. It is the fundamental premise of the first law of thermodynamics, which is most frequently stated as "energy cannot be created or destroyed."
Mass of the women => 60Kg
V1 => 8.7 m/s
v2=> 1.4m/s
Conservation of energy:
Kinetic energy 1 = Kinetic energy 2 + Potential energy
1/2 m v1^2 = 1/2 m V2^2 + mgh
V1^2 -v2^2/2 xg => h => height she raised

Both kinetic energy and momentum is conserved in this hit since it is perfectly elastic. Vf = mV + M0 = (m + M)v is the speed of the block/bullet system after the contact.
In physics, an elastic collision is a collision between two bodies in which the total kinetic energy remains constant. In an ideal, elastic collision, there is no net conversion of kinetic energy into heat, noise, or potential energy. In physics, kinetic energy (KE) is the energy that an object has as a result of its motion. Both kinetic energy and momentum are conserved in this hit since it is completely inelastic. Vf = mV + M0 = (m + M)v is the speed of the block/bullet system after the contact. It is defined as the effort necessary to move a mass-based body from rest to the given velocity. in kinematics and everyday usage.

 A race car's velocity decreases from 26 m/s to 5 m/s over a 9 second time interval. What
is the car's average acceleration?
2.3m/s^2 is the car's average acceleration.
Describe acceleration.
Acceleration is the term used to describe how quickly velocity and speed change over time. It is referred to as accelerating when something changes its rate of motion. Because the direction is constantly shifting, motion on a circle accelerates even at constant speed.
According to Newton's Second Law, an object's acceleration is determined by the total force acting on it. Meters per second squared (m s2) is the unit of acceleration in the SI system. The distance an object travels in a specific amount of time is referred to as its speed.
v = u + at
v = 5m/s
u = 26m/s
t = 9sec
5 = 26 a*9
a = -21/9

Consider Earth to be stationary, and the moon as orbiting Earth in a circle of radius R. If the masses of Earth and the Moon are ME and Mm, respectively, which of the following best represents the total mechanical energy of the Earth-Moon system?
Total mechanical energy of the Earth-Moon system=[tex]-\frac{GM_{e} M_{m}}{2R}[/tex]
Keeping in mind Kepler's first law, the planets orbit the Sun in elliptical fashion. This implies that as a planet orbits the Sun, the separation between the centres of masses, r, will change. As r varies, this causes a change in the planet's gravitational potential energy.The system's overall mechanical energy is crucially stable throughout its orbit. A planet's gravitational potential energy will drop as it orbits in a position close to the Sun, but its velocity and kinetic energy will grow. The system's overall mechanical energy is always constant because the increase in kinetic energy balances off the system's loss in gravitational potential energy.
Total potential energy of earth and moon=[tex]-\frac{GM_{e} M_{m}}{R}[/tex]
Velocity of moon=[tex]\sqrt\frac{GM_{e} }{R}[/tex]
