What is relationship between work force and motion

Net force is required to change the motion of an object, or accelerate the object. Often forces are balanced, so net force = 0, so motion does not change.
Work is in the same units as energy, not force. Work is related to force by
W = F*d*cos(theta) where F is the applied force, d is the distance through which the force has been applied, and theta is the angle (if any) between the force and the distance.
For example if a 100 Newton vertical force is applied to lift an object to a table 5 meters above the starting point, 500 Newton*meters, or 500 joules, of work have been done.

it's by newton's 1st law (an object at rest will remain at rest or of uniform motion in a straight line unless acted by an unbalanced force) and 2nd law (change in motion is directly and inversely proportional to the applied force and the mass respectivelyand is in the same direction as the applied force) of motion....
work is a force acting upon an object to cause a displacement....
a vertical force DOES NOT DO WORK horizontally ...

Gen. C. Yeager was the first to exceed the sound barrier in level flight over Edwards AFB flying a Bell X-1 in 1947. I think he would be the first to admit that he did some things back then that would have gotten him in a lot more trouble today. But back then, that was a whole lot of force and a whole lot of motion.

motion is a force in itself once in motion its easy to keep in motion . it takes force to change motion or to start motion a car has brakes or gas peda/ steering wheel airplanes has thrust so do rockets
