No. A rock rolls down a hill due to the force of gravity, also known as gravitic force.
The force stopping an object from rolling down a hill is friction. Friction occurs between the object and the surface of the hill, creating a resistance that opposes the object's motion. It is this frictional force that prevents the object from sliding or rolling down the hill uncontrollably.
The main forces involved in the ball rolling down the hill would be gravity, which is pulling the ball downhill, and friction, which is resisting the ball's motion and slowing it down. Additionally, if there's wind or air resistance, that force would also be acting on the ball.
The net force acting on a car rolling down a ramp is the result of the gravitational force pulling it downwards and any frictional forces resisting its motion. Generally, the net force will be equal to the component of the gravitational force parallel to the ramp minus the frictional force.
If friction did not exist, the ball would continue rolling indefinitely without slowing down or stopping. Friction is the force that opposes motion on surfaces, so without it, the ball would not experience any resistance to slow it down.

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).

Friction
Generally, only two forces act on a rolling ball. Gravity and friction (there has to be friction because without it, the ball would just slide). These are pointed directly in the x and y directions. If the ball is rolling down a slope, you can use trigonometry to find the force components.

A ramp exerts no force, just gravity.
The net force acting on a car rolling down a ramp is the result of the gravitational force pulling it downwards and any frictional forces resisting its motion. Generally, the net force will be equal to the component of the gravitational force parallel to the ramp minus the frictional force.

It involves the forces of Gravity. It also involves Friction and Inertia.

It will not, unless it is acted upon another force. If it's rolling on something, then friction will stop it (the ball rubbing on the table slows it down).
The force of a skateboard rolling down the sidewalk is primarily due to the push-off force provided by the skater's foot. Additionally, factors such as gravity, friction between the wheels and the sidewalk, and air resistance also contribute to the overall force propelling the skateboard forward.
