Gravity depends on mass, not on size or density.
Gravity is a force of attraction between two objects that have mass. The force of gravity is proportional to the product of the two masses and inversely proportional to the square of the distance between them. Therefore, the more massive an object is, the stronger the gravitational force it exerts.
Size and density are not directly related to gravity. Size is a measure of how big an object is, and density is a measure of how much mass is contained in a given volume. They do not affect the strength of the gravitational force. An object's size or density may affect the gravitational force acting on it, but only through their effect on the object's mass.
So, gravity depends on mass, but not on size or density. The gravitational force exerted by an object is proportional to its mass, regardless of its size or density.

What is angular momentum called?.
The rotational equivalent of linear momentum, angular momentum, is also known as Rotational Momentum or Moment of Momentum.
What is angular momentum?Angular momentum is the rotational equivalent of linear momentum in physics. It is an important physical quantity because it is a conserved quantity—in a closed system, the total angular momentum remains constant. Both the direction and magnitude of angular momentum are conserved. The property of any rotating object given by moment of inertia times angular velocity is defined as angular momentum. It is the property of a rotating body determined by the product of the rotating object's moment of inertia and angular velocity.

what is the standard unit for measuring temperature in the metric system?
The metric system uses Celsius as the primary unit of measurement for temperature.
Nearly all nations in the world use the metric system as their official unit of measurement, which includes Celsius. The Celsius scale is used to measure temperature in most scientific disciplines. The freezing point of water is zero degrees Celsius, and the boiling point is one hundred degrees Celsius. By the middle of the 20th century, Celsius, the most widely used temperature unit in the modern metric system, had been adopted by the majority of the world. Anders Celsius, a Swedish astronomer, created the Celsius scale in 1742.

what is the loudest sound ever recorded and what was its specific measurement?
The loudest sound ever recorded was the Krakatia volcano eruption and its specific measurement is 194dB.
The loudest sound ever recorded was due to a volcanic eruption that occurred on an Indonesian island named Krakatoa. The eruption occurred on 27th August 1883. The explosion led to a tsunami with waves as high as 46m thereby causing almost two-thirds of the island to collapse. The height of the waves was so high that they could rock the ships as far as South Africa. At a sound as high as 194 dB, a complete vacuum is created as the energy in the waves of sound starts distorting. At this position the sound waves while moving start pushing the air rather than moving through the air. This pushing away of the air leads to formation of the pressurized wall of moving air.

Definition of MassMass was first discovered by Sir Isaac Newton through research on the gravitational and inertial properties of objects he developed. Newton was an English physicist, mathematician, chemist, astronomer, natural philosopher, and theologian.
Mass can be interpreted as a measure of the number of particles contained in a substance or object. Mass is also one of the principal quantities that shows the size of the inertia of an object.
Mass becomes an intrinsic property of an object, so that wherever the object is, the mass value will remain the same. If it is based on the effect of the object on the direction of motion, mass is classified as a scalar quantity (only has value).
Mass has units in the International System , namely kilograms (kg). These units can be further reduced to grams (g), or milligrams (mg). Generally, mass is measured using a balance, for example a three-arm O'hauss balance, a digital balance, and a two-arm analytical balance.
