Unit 1 - Kinetics
9/26/18
Words to know
position: where an object is, in terms of a well-chosen origin.
distance: how far an object actually moves
displacement: an object's change in position
velocity: displacement over time
vector: has both magnitude and direction
scalars: has only magnitude (just a number)
acceleration: change in velocity / time
speed: how fast
Formulas
slope: m =y x
velocity: v = xt
speed: s = dt
position: x = vt + initial position
