Newton's 3 Laws

"A man may imagine things that are false, but he can only understand things that are true, for if the things be false, the apprehension of them is not understanding."~ Isaac Newton

Just like in Newton's 1st law this soccer ball is being used. The soccer ball is remained at rest in the first picture until force was applied by kicking it, that caused the soccer ball to move and stay in motion until it hit the goal.

Newton's 3 Laws of Motion!

1st Law- States that an object in motion stays in motion and an object at rest stays in rest unless acted upon by external force. This means that if an object is moving then it will continue to stay moving. If an object that is not in motion than it will remain that way unless someone or something adds force to it, or cause it to move. 2nd Law- This law states that when a force acts on an object, it will cause the object to accelerate. The law means that it takes more force to move a heavy object than it does to move a light object. 3rd Law- The law states that for every action, there is an equal and opposite reaction. What this means is that pushing on an object causes that object to push back against you, the same exact amount, but in the opposite direction.

The Laws!

As in Newton's 3rd law the rocket’s action is to push down on the ground with the force of it’s powerful engines. The reaction is that the ground pushes the rocket upwards with an equal force. Another example is a heavy ball or object. If you try to throw it away from you, the force exerted will push back on you, possibly pushing you backward onto the ground.

According to Newton's 2nd Law kicking a bowling ball vs kicking a soccer ball relates. If you kick the bowling ball it’s going to hurt your foot because it has more mass than a soccer ball that is lighter and doesn’t hurt.
