Question

According to work energy theorem a particle of mass m when subjected to
external force the work done during displacement by all forces is equal to
change in during displacement.
a) Gravitational Energy
b) Mechanical Energy
c) Kinetic Energy
d) Potential Energy​

Answer 1

The correct answer is option : c)  Kinetic Energy

According to work energy theorem a particle of mass m when subjected to

external force the work done during displacement by all forces is equal to

change in Kinetic Energy during displacement.

Work done (W) = change in kinetic Energy(KE)

  W = ΔKE = $(\frac{1}{2} *mv_{f} ^2) - (\frac{1}{2} *mv_{i}^2 )$
