MMS Force and Motion

Force A push, pull, or change in direction
magnitude the strength of a force (greater magnitude = bigger force)
gravity the force of 1 object with mass pulling on another object with mass
mass the amount of "stuff" or matter in an object
Newtons The unit of measurement for force (N)
Acceleration speeding up, slowing down, or changing direction
Speed Distance divided by time or how far an object travels in a certain amount of time
Friction A force that exists between two objects and is always the opposite of motion.
Balanced Force When an object is NOT accelerating (speeding up, slowing down, or changing direction)
Unbalanced Force When an object is accelerating (speeding up, slowing down, or changing direction)
Newton's 1st Law The Law of Inertia - an object that is moving will keep moving and an object at rest will stay at rest UNLESS another force acts on the object
Newton's 2nd Law F=m x a When mass increases, force will increase. When acceleration increases, force will increase.
Newton's 3rd Law For every force there is another force acting in the opposite direction but equal in size
