scalar
A quantity that has only magnitude ex. speed, distance, time
vector
a quantity that has both magnitude and direction ex. displacement, velocity, acceleration, force
event
something that happens at a given position and time
standard unit of time
second
disance
the amount of space seperating two positions (d)
displacement
Distance and direction of an object's change in position from the starting point. (d with an arrow above it)
speed
the rate at which an object's distance is changing (v)
velocity
the rate of change of position or displacement
uniform motion
an object that has a constant velocity
acceleration
rate of change of velocity (non-uniform motion)
acceleration-time graph example
projectile motion
the object flies through the air with a two dimensional trajectory (both horizontal and vertical)
