Newton's 1st Law
An object at rest will remain at rest and an object in motion will remain in motion, unless acted on by an unbalanced force.
Also called the "Law of inertia
Inertia
The tendency of an object to resist any change in motion
Newton's 2nd Law
Acceleration is produced when a force acts on a mass.
Force
a push or pull on an object; measured in Newtons (N)
Mass
The amount of material/matter in an object
Friction
A force that opposes or slows down motion
Gravity
A force that always attracts or pulls objects toward each other without direct contact or impact
Newton's 3rd Law
For every action, there is an equal and opposite reaction.
Balanced forces
Equal forces acting in opposite directions causing no change in motion
Unbalanced forces
forces not equal in size that cause the motion or direction of an object to change
net force
the sum of all forces acing on an object.
momentum
The product of an objects mass and velocity
Weight
A measure of the force of gravity on an object
mass
A measure of the amount of matter in an object
kinetic energy
Energy of motion
potential energy
stored energy or energy of position
