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
