False
Speed depends on distance and direction.
False
Speed equals distance multiplied by time.
False
The SI unit for acceleration is km/s^2
False
The formula for acceleration is a = Δt/Δv.
False
A change in velocity can occur without a change in speed.
True
Acceleration shows how quickly velocity changes.
