Question

On what factors does the kinetic energy of a body depend?

Answer 1

Hint: To answer the above question, we need to understand the concept of kinetic energy and the factors that allow us to measure the kinetic energy of a body. Kinetic energy is the energy of an object that is caused due to movement of the object.

Complete answer:
An object's kinetic energy is a measure of the work it can produce as a result of its motion. Kinetic energy is measured in scalar units. The magnitude of kinetic energy is the only way to describe it.
Because the square of the speed yields a non-negative integer and the mass cannot be negative, a body's kinetic energy cannot be negative. When the potential energy is at its lowest, the kinetic energy is at its highest. This happens when the mass is in equilibrium and the velocity is at its maximum.
We must apply force to accelerate an item. We must work in order to exert force. Energy is transferred when work is done on an object, and the object moves at a new constant speed. Kinetic energy is the energy that is transported and is determined by the mass and speed reached.
The formula of kinetic energy is:
 $ KE = \dfrac{1}{2}m{v^2} $
 $ m $ is the mass of the body.
 $ v $ is the velocity of the body.
Thus, we can conclude that mass and velocity of a body are the factors upon which the kinetics of a body depends.

Note:
Because the truck's mass is significantly more than the automobile's, a truck travelling down the road has more kinetic energy than a car travelling at the same speed. Because water has a specific velocity and mass, a river moving at a certain speed contains kinetic energy. An asteroid colliding with Earth has a lot of kinetic energy.
