Question

8. Define kinetic energy.
Derive its formula. On what
factors does the value of
kinetic energy depends.​

Answer 1

Answer:

To accelerate an object we have to apply force. To apply force, we need to do work. When work is done on the object, energy is transferred and the object now moves with a new constant speed. The energy that is transferred is known as kinetic energy and it depends on the mass and speed achieved.

The definition of kinetic energy in Physics

“Kinetic Energy is the energy possessed by the body by virtue of its motion”

The kinetic energy equation is given as follows:

KE=12mv2

Answer 2

Answer:

It is defined as the energy possessed by a body by virtue of its motion.
