An object is moving along some path. the total work done on the object during this process is zero.
The Attempt at a Solution
A the speed of an object has decreased.
B the speed of the object may have changed.
C the object must be moving in a circle
D the velocity of the object must not have changed
E the speed of the object has not changed
F the velocity of the object may have changed
I chose answer D and E. From what I understand so far work is zero when the Force is perpendicular to the displacement.
would speed and velocity changed, when the work of an object is zero?
