Work was done the gravity on a rocket going perpendicular upwards. Zero work: When force and displacement are perpendicular to each other, or when force or displacement is zero.
Hope that helps

Answer:
Zero work: When force and displacement are perpendicular to each other, or when force or displacement is zero.
Explanation:
A simple example of zero work is when you stand holding a bag in your hands and do not move it. Your hands apply a force on the bag to balance the force of gravity exerted on it but since there is no displacement of the bag, the work done on it by you (your force) and also the gravity is zero.
