what is kinematics?
description of the motion of objects without referring to any forces that may cause the motion
what is dynamics?
explains the causes for the motion that kinematics describes
what is energetics?
transformation of one kind of energy into another form of energy
what is distance (Δd)?
linear space between two points
what is position (d)?
where an object is relative to a point of reference
what is time (Δt)?
interval between two events
what is uniform motion?
speed and direction are constant
what is non-uniform motion?
speed and direction are not constant
what is speed (V)?
rate at which an object is moving
what is uniform speed?
speed that remains changed and constant
what is instantaneous speed?
speed of an object at a given instant in time
what is instantaneous speed measured by in a vehicle?
a speedometer
why do we calculate an average speed?
variations in the actual speed may occur
what is the equation for average speed?
Vave = Δd / Δt
