Question

Work done by the resultant force is always equal to a change in kinetic energy.

• A. True
• B. False

Answer 1

The correct option is A True

1. The relation between work done and change in kinetic energy is given by the work-energy theorem.
2. The work-energy theorem states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle.
3. The mathematically work-energy theorem is given below.
   $W_{net}=\Delta KE=K{E}_{final}-K{E}_{initial}$
   

Hence, the given statement is true.
