Newton's Third Law

What does Newton’s Third law state?

When two objects interact, the forces they exert on each other are equal and opposite (the same magnitude, different directions)

What is the name of the force that causes another object to exert an equal and opposite force? 


Normal contact force

Most of the time when you push an object, or an object pushes you there is movement (either from you or the object and sometimes both,) how so?


The movement of an object depends on the mass

• if you push an object with a very large mass, it will most likely cause you to be pushed back - even though you are exerting the same amounts of force

• however, if you push an object with a much smaller mass, the object will be the one to move
