2.
NEWTON'S FIRST LAW
An object at rest stays at rest unless acted upon an outside force.
Examples:
Bowling ball rolling down a lane
Seatbelts
Airbags
3.
HOW IS MASS RELATED TO INERTIA?
Small mass=less inertia
Large mass=more inertia
4.
NEWTON'S SECOND LAW
The acceleration of an object is directly proportional to the net force on the object and inversely proportional to the objects mass.
Examples:
Pushing a swing with a skinny person vs heavier person
Kicking a chair out from under a skinny person vs heavier person
Pushing a sled with a skinny person vs heavier person
5.
FORMULA FOR 2ND LAW
F=MXA OR FORCE=MASS X ACCELERATION
6.
SI UNIT FOR FORCE
NEWTON
7.
NEWTON'S THIRD LAW
For every action force, there is an equal and opposite reaction force
Examples:
Shooting a gun and then falling backwards
Pushing of a skateboard and moving forward
Slamming on the breaks and jerking forward
8.
FORMULA FOR MOMENTUM
P=MXV OR MOMENTUM=MASS X VELOCITY
