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

Then one force is overcoming another force, and the object moves.
When a force moves something parallel to the direction of that force, it is called translational motion. In translational motion, the object moves along a straight path without rotating or changing orientation.
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.
when an object moved in a circular path it accelerates toward the center of the circle as a result of
rolling friction, air resistance and gravitational force
Gravity is the fundamental force that moves or accelerates soil and regolith down a slope. The force exerted by gravity pulls loose materials downslope due to the force of gravity acting on their mass.
torque turns the wheels which moves internal combustion/electric cars. In a jet car, thrust is the force the moves the car.

Rock moves upward along faults to form a mountain range.

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.
The path a revolving object moves along is called a circular or elliptical trajectory, depending on the shape of the object's orbit. The object continuously moves around a central point due to the force of gravity or other factors influencing its motion.
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.
Well, I was taught that it was centripetal force, but that was a long time ago.
