Why do cars need petrol if uniform motion requires no resultant force?
A moving object always experiences drag, a unbalanced force slowing it down. Thus it needs a force provided by the engine to counteract this force. The engine doesn't go without petrol (or some other appropriate fuel) so a car needs that as well.
What is meant by the term driving forces?
driving force is the opposite force against (air resistance, friction, drag, tension) it is the force provided by some kinda potential, A car engine provides driving force or in fact any kinda force to keep the object moving
Electromotive force is usually provided by a?
It is usually provided by a battery or generator.
The forward force from a plane's engine is?
The forward force from a plane's engine is thrust.
Hot to force car engine to stop?
There are several ways to force an car engine to stop. One way to force the engine to stop is to disconnect the battery. Another way to force the engine to stop is to turn off the ignition.
Electromotive force is usually provided by a what or what in an electric circuit?

The forward force from a plane's engine is called?
The forward force from a plane's engine is called THRUST.
Which component uses the force of engine exhaust to force the compressed air and fuel into the engine.?
A turbocharger.
If the force from the engine is bigger than the force of the air resistance?
The vehicle accelerates, assuming the engine is in a vehicle.
What provides the force for thrust?
The engine provides force for thrust.
Where does force needed to keep planets orbiting the sun come from?
The force is provided by the Sun's gravitational attraction.
