Any force will make things move, as long as there is no other force to counter it. (Such a counter-force may be present in the form of friction.)
gravity? inertia? momentum? one of those?
Any force, as along as its unbalanced. If the object was acted upon a balanced force its velocity would stay the same whether it was moving or not.
An Electro Motive Force "EMF".
gravitational force
Friction does not move things. Friction is the force that opposes motion between two objects that are touching. Not enough friction allows for things to move, depending on what kind of friction; the less force it has.
Friction makes it harder to move things.
Inertia makes things move.
Any force can be used to make something move. It is kind of the nature of forces.
gravity? inertia? momentum? one of those?
An external force (like magnetic field or gravity)
When a force makes an object move, work is done.
The natural force wind makes the leaves plants move.
the air makes living things move and wind.
Any force, as along as its unbalanced. If the object was acted upon a balanced force its velocity would stay the same whether it was moving or not.
