Question

define kinetic energy. Derive an expression for it?​

Answer 1

Explanation:

The kinetic energy of a body is the energy that it possessed due to its motion. Kinetic energy can be defined as the work needed to accelerate an object of a given mass from rest to its stated velocity. Kinetic energy depends upon the velocity and the mass of the body. ...

Answer 2

Answer:

Answer:-

The kinetic energy of a body is the energy that it possessed due to its motion. Kinetic energy can be defined as the work needed to accelerate an object of a given mass from rest to its stated velocity.

Derivation:-

F=m(2dV2). As we know that Work done =Fd. Putting the value of F, we get, Workdone=(2dmV2)(d)=(2mV2)=21mv2. Therefore, the expression for kinetic energy is 21mv2.
