What is displacement?
the difference between the initial and final position
What is velocity?
the rate of change of displacement with respect to time
What is acceleration?
the rate of change of velocity with respect to time
What are the kinematic equations?
v = v₀ + at and v² = v₀² + 2ax
What are scalar quantities?
those with magnitude but not direction
What are vector quantities?
those with magnitude and direction
What is the equation for acceleration?
av = (v’ - v) / ΔT
What is the equation for velocity?
v = d/t
