we have a ball moving at a constant velocity, and a ball not moving
Newton's Second Law
Force is equal to mass times acceleration of an object
F=ma

here we show that the force of the ball dropping and bouncing is equal to the mass times acceleration, -9.8 meters per second
also a ball being thrown to different distances
Newton's third law
For every action there is an equal and opposite reaction.

in this example we have a chest bump of John and Connor. They weigh almost exactly the same, and equally fall back
if it wasnt true an object could stick to another or collide and fall straight down.
