Force is simply a push or pull that tends to change the state of a body. An object will move from its position when a force is applied to it. In general, force results in the motion of an object.
While jogging, the man is applying force to his feet to move from one place to another.

Rest:
An object is said to be in a state of rest when there is no change in its position with respect to time.
Initially, an object is stationary, meaning it is completely at rest. But, when you push or pull an object to any side, it moves out of its rest position, resulting in motion.

Motion:
An object is said to be in the state of motion when its position changes with respect to time. From tiny atoms and molecules to larger stars and galaxies, everything is in motion.
Example:
Flying birds, moving cars, the flow of blood through veins and arteries.
