A body at rest cannot have:

A) Momentum

B) Kinetic energy

C) Both A) and B)

D) Equilibrium

The correct option is C) Both A) and B).

When a body is at rest, it cannot have kinetic energy and momentum because kinetic energy is associated with the motion and momentum is defined as the product of the mass of the body and velocity.

For a body to be at rest and in equilibrium, the following are the two conditions:

  • Sum of all the forces acting on the body must be equal to zero.
  • The resultant torque must be equal to zero.
