What is a force?
A push or pull
What is a net force?
The combination of all forces acting on an object
Balanced force
Forces combine and give zero net force
Unbalanced force
Produce nonzero net force
Gravitational force
Force between 2 objects
Electromagnetic force
Includes electric and magnetic forces
Nuclear forces
Forces within nucleus of atom. Holds protons and neutrons together
Frictional force
Tend to stop the objects motion by dispersing its energy as heat
Examples of frictional forces
Sliding, Rolling, static
Newtons 1st Law
Object at rest will stay at rest and an object in motion will stay in motion unless acted upon by a outside force
Law of INERTIA
The tendency of an object to resist a change in motion. AKA NEWTONS 1st LAW
Newtons 2nd Law
The unbalanced force acting on an object equals the objects mass acceleration F=MA
Newtons 3rd Law
For every action force there is an equal and opposite reaction force. Example is a rocket ship or a swimmer
Mass
The amount of matter in an object(THIS DOES NOT CHANGE)
Weight
Force of gravity acting on an objects mass; changes based on its location
Free fall
The Only force acting on an object is the earths gravity; in the absence of mass all objects accelerate toward earths surface at the same rate regardless of mass
Terminal velocity
When an object stops accelerating due to weight and air resistance being equal- W=MG
