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

When an unbalanced force acts on an object the?
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?
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.
How does force lead to motion?
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.

What is the basic force that moves or accelerates soil and regolith down a slope?
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.
When a car moves on a road which force actually moves the car?
torque turns the wheels which moves internal combustion/electric cars. In a jet car, thrust is the force the moves the car.

Why no work is done by the force acting on Venus as it moves?
No work is done by the gravitational force acting on Venus as it moves in its orbit because the force is always perpendicular to its direction of motion. Work is defined as the product of force and displacement in the direction of the force; since the gravitational force acts towards the Sun while Venus moves along a curved path, the angle between the force and the displacement is 90 degrees, resulting in zero work done.
What does it mean to sat that the net force determines an objects acceleration?
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.
What is the path a revolving object moves along?
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.
What happens as a tornado moves?
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.
