Questions with Complete Solutions
Acceleration (definition) - ANSWER-Acceleration is how quickly the velocity is changing
Acceleration (the formula) - ANSWER-acceleration = change in velocity/time taken
v (in the acceleration formula stands for...) - ANSWER-final velocity (the v in v-u/t)
u (in the acceleration formula stands for...) - ANSWER-initial velocity (the u in v-u/t)
Units of acceleration - ANSWER-m/s²
Distance-time graph - ANSWER-Tells you how far an object has moved and how long it
took
Gradient - ANSWER-Speed
Flat - ANSWER-Stopped/stationary
The steeper - ANSWER-The faster
Downhill - ANSWER-Going back to the starting point
Curves - ANSWER-Acceleration/deceleration
Steepening curve - ANSWER-Speeding up
Levelling of curve - ANSWER-Slowing down
Speed - ANSWER-distance / time
Distance - ANSWER-speed x time
Time - ANSWER-distance / speed
Velocity - time graph - ANSWER-Shows how an object changes velocity over a period
of time
Gradient (v-t graph) - ANSWER-Acceleration (v-t graph)
Flat (v-t graph) - ANSWER-Steady speed (v-t graph)
The steeper the v-t graph - ANSWER-The greater the acceleration/deceleration
