Everything that moves needs a force to get it moving
Force and gravity can increase your speed and acceleration
Gravity pulls objects towards each other, and it keeps us on earth
A moving object needs a force to change it's direction, slow it down, or make it stop
A force is any push or pull of an object. Anything that falls depends on a force called gravity
Friction happens when two surfaces rub against each other. On earth gravity and friction work together to slow things down and make them stop
Inertia - An object at rest tends to stay at rest, and an object in motion stays in motion unless a powerful force stops it. A still object needs a force to get it moving
The amount of acceleration that a force can produce depends on the mass of the object
Mass is the amount of matter in an object.
Every action involves a pair of forces. An action's force creates a reaction of equal force in the opposite direction
Centripetal Force - a force that acts on a body moving in a circular path and is directed toward the
center around which the body is moving.
Balanced forces acting opposite direction cancel each other
More force is needed to change the motion of an object
