How does an angle between the force applied and the direction of motion influence the work done or object?
Correct answer: B. Work is maximum when the angle is 0°
- A. Work is constant regardless of the angle
- B. Work is maximum when the angle is 0°
- C. Work is negative when the angle is 90°
- D. Work is 0 when the angle is 45°
Explanation
Work is maximum when angle is zero because cos 0 is 1.

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.
