what is motion? Why the objects in a collision can have different changes in motion??? PLEASE HELP

Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.

The law can be expressed this way: In a collision, an object experiences a force for a specific amount of time that results in a change in momentum.

Hope this helps

the action or process of moving or being moved.

"the laws of planetary motion"

Explanation:

A force is a push or pull that can cause an object to move, stop, or change speed or direction. 3. The greater the force, the greater the change in motion. ... Gravity (the earth's pulling force) and friction (the force between two surfaces) are common forces that work against motion.

like poles repel so keep pushing north to north and repels funny to see this
