Question

Short Answer Type 2 Q1. The velocity of a body moving in a straight line is inereased by applying constant force F, for some distance in the direction of motion. Prove that the increase in the kinetic energy of the body is equal to the work done by the force on the body ​

Answer 1

Answer:

w=F×S

=m×a×s.

=m($v^{2}- u^{2}$)/2

​ =mΔ^ 2/2

ue=1/2$mv^{2}$

ΔuE= 1/2$mv^{2}$-1/2$mu^{2}$
