The force F = M (mass) * a (acceleration) (Newton's second law of motion)
In metric units:
Force: N (= mass*g) where g is approx equal 9.81 m/s^2 (depends on location, Sweden=9.819 m/s^2)
mass: kg
acc: m/s^s
The force must be greater than the resistance. The resistance increases with increased speed! To power a car at 40MPH requires xHP, at 80MPH it requires 8xHP!
wind resistance (non linear!) (aka Cd)
rolling resistance (constant) (aka Cr)
etc

The car depends completely on the engine. The engine in the car does the work
& hence the car functions(move). The motion of the car is due to the motion of the wheels. For this motion the necessary force is the frictional force which is provided by the rough surface of the tyre & the road. Therefore a car can accelerate on a road due to the frictional force.
The wheels pushing against the road (the force of friction)
A shove on an open door will force it into movement (motion) and it will close. cw: Mass moves at a constant rate (including zero) when there is no force applied to it. With a force applied, the mass accelerates. Accelerates means it changes its motion.
Well, I was taught that it was centripetal force, but that was a long time ago.
The accelarator gets pushed and rubberbands push the car !
when an object moved in a circular path it accelerates toward the center of the circle as a result of
The wave traveling along a bullwhip is simply a mechanical wave. It's like the wave that travels along a jump rope or a fly fishing line when it's being cast. The user accelerates the handle of the bullwhip forward, and the rest of the whip moves along in response. It should be noted that the sudden reversal of the tip of the whip is what accelerates the end to supersonic speed. This creates the small sonic boom which we know as the crack! of the bullwhip. All of this action is the result of mechanical forces, or mechanics.

torque turns the wheels which moves internal combustion/electric cars. In a jet car, thrust is the force the moves the car.
There are many forces acting on a body. But, the moves because of the net force acting on it. So, we can say that the body accelerates because of net force acting on it only.
Rock moves upward along faults to form a mountain range.

When an object moves in a circular path, it accelerates toward the center of the circle due to the centripetal acceleration. This acceleration is necessary to keep the object moving in a curved path rather than in a straight line.

A tornado moves with its parent thunderstorm. As the tornado moves air flows into it and accelerates to great speeds. Objects caught in the path may be damaged or destroyed.

Thrust is a reaction force described quantitatively by Newton's second and third laws. When a system expels or accelerates mass in one direction the accelerated mass will cause a proportional but opposite force on that system.
