Question

According to work energy theorem, workdone by a force in displacing a body measures a) the change in momentum of the body b) the change in velocity of the body c) change in impulse of the body d) change in kinetic energy of the body​

Answer 1

Answer:

change in kinetic energy of the body

Explanation:

Solution:

According to work-energy theorem, work done by a force in displacing a body on a horizontal level measures the change in its kinetic energy.

Answer 2

Answer:

w = f * s cos theta

Explanation:

if a force applied on a object it will displace means the object is getting kinetic energy. why not change in momentum. because change in momentum is a vector quantity and if change the direction the displacement change and it can not be applies on work done theorem

anyway the d option is correct
