An outside force. An object at rest stays at rest unless acted on by an outside force.
Make it into a slingshot
Solar cells make objects move by using the power from the sun to generate power to move something.

You need Potential (stored) Energy
Make the "something" lighter when going agaiinst gravity (up).Make something heavier when going down.Make the force acting on the "something" biggerMake the "something" move easier through or on whatever it is moving through or on. Make it more aerodynamic, make any wheels spin easier etc etc.
when something moves it changes iitsopon
Something to make the electrons or other charged particles move - i.e., a voltage. Also, something through which the charged particles can move - usually a conductor. Usually a closed circuit is required.
Yes. To make something move, you have to add energy. An electric motor won't turn by itself.
Energy
If the car is broken, you have to move it with something that can carry the entire weight of the car....
In a car, a transmission system is needed because the engine does not make enough torque to make the car move.
A force is needed to start something moving and to stop it once it is moving. A force can make something speed up or slow down. Friction is a force generated when surfaces move across each other.
