Question

Give one example when accelaration and displacement are perpendicular to each other

Answer 1

Explanation:

Since the force is acting parallel to the direction of motion, the angle is equal to zero and our total work is simply the force times the displacement in the x-direction. In the second scenario, the box is being pushed at an angle of 45 degrees to the x-direction; and thus also a 45 degree angle to the y-direction.
