Speed - Velocity - Acceleration - Quiz 1. What is the speed of an object which is stationary? Infinite Very fast Slow Zero Answer:Zero 2. What unit is velocity measured in? m/s m/v s/d m x v Answer:m/s 3. Velocity Is speed in a circle Is always the same as speed Is the opposite of speed Is speed in a certain direction Answer: Is speed in a certain direction 4. Constant velocity means That the velocity of the object does not change That the object is getting faster That the object is getting slower That the velocity of the object is constantly changing Answer:That the velocity of the object does not change 5. Acceleration is A faster time A longer distance A change in velocity A louder noise Answer: A change in velocity 6. Which equation connects acceleration, velocity and time? a = v x t v = t x a t = a ÷ v a = (v-u) ÷ t Answer:a = (v-u) ÷ t 7. Which equation connects acceleration, force and mass? a = f x m f = m x a m = a x f a = (f + a) x m Answer: |
