Force = Mass x Acceleration
You jump on a trampoline which will push back on you and force you into the air for a few seconds.
If you use a greater force to kick a soccer ball it will move faster.
Soccer ball will stay on the floor until someone kicks it.
Also known as the Law of Inertia.
For every action there is an equal and opposite action.
Newton's 1st Law of Motion
Newton's 2nd Law of Motion
