Work will be maximum when the angle between force and displacement is
Correct answer: A. 0
- A. 0
- B. 90
- C. 180
- D. 4
Explanation
Work done by a force is given by the dot product of force and displacement:W = F . S = F S cos θWhere:W is the work doneF is the forceS is the displacementθ is the angle between force and displacementThe work done is maximum when cos θ is maximum, which is when θ = 0°. In this case, the force and displacement are in the same direction, and the work done is equal to the product of the magnitude of the force and the magnitude of the displacement.

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.
