Question

According to work energy theorem, the increase in the kinetic energy of a moving body is equal to ______ by a force acting in the direction of the moving body.

Options

• displacement

• velocity

• acceleration

• work done

Answer 1

According to work energy theorem, the increase in the kinetic energy of a moving body is equal to work done by a force acting in the direction of the moving body.

Explanation:

Work-energy theorem states that the work done by a force acting in the direction of motion equals the increase in kinetic energy. Displacement, velocity and acceleration are not measures of energy transfer.
