Friction
yes it does. i just did the experiment.
Sliding friction requires more force to overcome its friction.
Sliding Friction
You can move a trolley with a magnetic force (e.g. use magnets to draw the trolley away from it's original position - assuming it is made of a magnetic material), a gravitional force (e.g. rolling the trolley down a ramp) or with an applied force (e.g. pushing the trolley).
