speed distance divided by Time
force a push or pull
equilibrium when a state/system becomes squal or balanced
friction the force that opposes motion between two surfaces that are in contact with eachother
motion a change of position in an object
Balanced force Equal forces acting on eachother
Unbalanced force unequal forces acting on each other; results change in the object's motion and follows the larger force
velocity speed and direction of a moving object
mass an amount of matter in an object
acceleration change of velocity over time
inetria an object's tendency to resist change in motion
weight A measure of force + Gravity on an object
w=m*a
gravity force of attraction between any two objects
potential energy When energy is stored because the object is still
Kinetic energy when energy is applyed to a particle or object because it is moving
