Question

For a motion with uniform velocity, write expression for 'v' in terms of 's'.​

Answer 1

Answer:

Explanation:

Kinetic Energy:

The energy possessed by an object due to its motion is called as kinetic Energy.

Derivation:

Let us consider an object of mass " m " which is at rest on smooth horizontal plane.

Let a Force, F acts on the object and let the object from rest moves from point A to point B and covers a displacement S. The WORK Done by Force on the object

is :

Workdone = Force x displacement.

W=FxS

_(1).

From third equation of motion;

V^2 -U^2 =2aS

S= V^2 -U^2/2a,

(2)

By Newtons second law of motion:

F= ma

From equation 1 and 2

W=m*a* (V^2- U^2)/2a

As we have assumed object is at rest, u=0

W=m*V^2/2
