When force and displacement are in the same direction, the kinetic energy of the body
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remains constant
- D. Becomes zero
Explanation
When force and displacement are in the same direction; the kinetic energy of the body increases. The increase in kinetic energy is equal to the work done on the body.

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
