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
