Question

when the angle between the force and displacement is 0° when the angle between the force and displacement is 180° when the angle between the force and displacement is 45° when the angle between the force and displacement is 90°

Answer 1

when the angle between force and displacement is 0° then the work done is maximum

when the angle between force and displacement is 180° then work done is negative

when angle between force and displacement is 45° then done is positive

when angle between force and displacement is 90° then work done is zero
