The work done is zero when the displacement is normal to the direction of force.
A non-zero force is acting on a body but work done is zero. Which of the following statements justify the above situation? 1.Displacement is zero. 2.Force is perpendicular to the direction of displacement. 3.Force is parallel to displacement. 4.Force is opposite to the direction of displacement.
When force applied is not in the direction of displacement of an object, is there any work done?
Why work is said to be negative when force is applied opposite to the direction of displacement?
How is the work done by a force measured when (i) force is in direction of displacement, (ii) force is at an angle to the direction of displacement?
