Force
A push or pull on an object
Unbalanced Force
Forces that have a net force that is not zero (object will move)
Balanced Force
Forces that have a net force of zero (the object is still)
Net Force
A measure of all the Forces acting on an object
Inertia
The tendency for an object to not change its movement
Friction
The force that acts on an object to stop its motion
Free Fall
When Gravity is the only force acting on an object
Air Resistance
The friction caused by an object falling through air
Gravity
The force that pulls things toward Earth
Newton's 1st Law of Motion
Objects in motion stay in motion, objects at rest stay at rest unless acted on by an outside force
Newton's 2nd Law of Motion
Force = Mass x Acceleration
By increasing or decreasing the mass or acceleration of an object you change the force applied by that object
Newton's 3rd Law of Motion
For every action, there is an equal and opposite reaction
