Newton's 3 Laws of Motion Notes

​Inertia kept penny in place.

Force placed only on card.

Examples: table cloth trick flying forward when brakes are applied

Multiple Choice

What does Newton's First Law State?

• Objects in motion stay in motion and objects at rest stay at rest unless acted upon by an outside force.

• Objects in motion always stay in motion and objects at rest always stay at rest.

• Objects will in motion will only move other objects in motion.

• Objects at rest can never be moved.

Multiple Choice

According to Newton's First Law more mass equals....

• more inertia

• less inertia

• no inertia

• nothing.

Multiple Choice

According to Newton's First Law less mass equals....

• more inertia

• less inertia

• no inertia

• nothing.

​To increase acceleration, the mass has to decrease or the force has to increase.

If mass increases force increases.

Examples: Tow truck

piggyback ride

pushing a car

pulling a wagon

Multiple Choice

What is Newton's Second Law?

• force is imaginary

• force equals mass times mass

• force equals mass times acceleration.

• force equals acceleration times inertia

Multiple Choice

True or false: A chair will accelerate faster with a 195 pound person and slower with a 65 pound person.

• True

• False

​Equal but opposite reaction Action: air expelled out back of balloon Reaction: balloon goes forward

Example: jumping off a boat

kicking a soccer ball

rocket

bumper cars

Multiple Choice

What is Newton's Third Law?

• for every action there is the same reaction.

• For every action there is an equal but opposite reaction.

• for every action there is no reaction.

• For every action there is a reaction that is not related to the action.
