I think that in order for work to be done, the object must move in the direction of the force and move over a distance.
Rolling friction .<span> the force that slows down the movement of a rolling object</span>
sliding friction.
Sliding friction : The opposing force that comes into play when
one body is actually sliding over the surface of the other body
is called sliding friction. e.g. A flat block is moving over a
horizontal table.
Kinetic or dynamic friction: If the applied force is increased further
and sets the body in motion, the friction opposing the motion is called
kinetic friction
Explanation:
F = MA
200 = 100 * A
A = 200/100
A = 2m/sec^2
