HI BUDDY...
YOUR ANSWER IS:
Work is done whenever the given 2 conditions are satisfied;
▪A force acts on a body
▪There is displacement of the body by the application of force in or opposite to the direction of force.
If the direction of the force is perpendicular to displacement, then the work done is zero.
When a satellite moves around the earth ,then the direction of force gravity on the satellite is perpendicular to its displacement .Hence the work done on the satellite by the earth is zero.
See, on earth, it is not possible that a force is on acting on an object.
For example, if we are at rest, then we remain at rest because frictional force is acting upon us.
Well, your question should have been that can there be displacement if an object remains at rest or at motion.
I'll answer both....
So an object doesn't have any displacement if remains because no distance is covered and displacement is the shortest distance between two points IE the initial and final points.
Now, if an object is at motion, it will have some displacement, which may be negative, positive or zero...
if you have more doubts ask me in the comment box and if you like my answer please mark it brainliest
HOPE IT'LL HELP YOU
