The amount of kinetic energy of a moving object has dependence on its mass and its velocity.

Further explanation:

The possession of energy in a body due to its motion is known as the kinetic energy of that body.

Concept used:

The capacity of a body to do work is known as its energy. Energy can be in any form either chemical energy, potential energy, mechanical energy, etc.  

Law of conservation of energy states energy can neither be destroyed nor be created. It can only be transformed from one form of energy to other form.

Example: A cyclist ride a bicycle in this chemical energy is converted into mechanical energy, etc.

There are different types of energy:

•Potential energy: The possession of energy due to the height of the object is called potential energy. It also depends on the mass of the object and acceleration due to gravity.

•Kinetic energy: the possession of energy due to the motion of the body is known as its kinetic energy. It is also defined as the product of mass and the square of its velocity.

The expression for the kinetic energy is given as.

Here, is the mass of the object, is the velocity of the object and is the kinetic energy of the object.

Above expression indicates that the kinetic energy is directly proportional to the mass of the object and to the square of the velocity of the object.

Thus, the kinetic energy of a moving object has dependence on its mass and its velocity.
