Newton’s First Law of Motion Newton’s Second Law of Motion Newton’s Third Law of Motion

Newton’s First Law of Motion • An object at rest, remains at rest and an object in motion, stays in motion, unless acted on by an unbalanced force.

This is also known as the Law of Inertia • Inertia is defined as the tendency of an object at rest to stay at rest, and an object in motion to stay in motion. In other words, an object wants to remain in it’s current state of motion.

Newton’s Second Law of Motion • The unbalanced force acting on an object equals the object’s mass times its acceleration.

Big Bang Theory Clip Look at the white board behind Sheldon. There actually a lot of terms and equations you learn in this class.

Force = mass x acceleration F m Fa a

• If two cars are in a ditch, and one is a mini cooper and the other is a suburban, which will take more force? Why? • If you throw a 6 pound bowling ball down the lane as hard as you can, and then you throw a 16 pound bowling ball as hard as you can down the lane, which bowling ball will have the greatest acceleration? Why?

Newton’s Third Law of Motion • For every action force, there is an equal and opposite reaction force. (These forces are equal but still unbalanced. )

The action and reaction forces act on two different objects. • The wall pushes on my hand, my hand pushes on the wall. What is receiving my force? What is receiving the walls force? The forces are of the same magnitude, but the receivers of the force are opposite. Which diagram shows Newton’s Third Law?

An equal but opposite reaction can also look like this: It looks like this with rockets or airplane engines.
