The first law of inertia says that an object’s speed will not change unless something makes it change.
Newton's First Law of Motion
Place the hard boiled egg on its side and spin it. Put your finger on it gently while it is still spinning in order to stop it. Remove your finger when it stops.
Place the raw egg on its side and spin it. Place your finger gently on the egg until it stops. Once you remove your finger, the egg should start to spin again. The liquid inside the egg has not stopped so it will continue to spin until enough force is applied.
The second law: the strength of the force equals the mass of the object times the resulting acceleration.
Newton's Second Law of Motion
Drop a rock or marble and a wadded-up piece of paper at the same time. They fall at the same rate of speed, but the rock's mass is greater so it hits with greater force.
Finally, the third law says that for every action there is a reaction.
Newton's Third Law of Motion
Pull one ball or swing back and let it go.
It will swing into the other balls making the ball at the other end swing.
