5
Q
- Average speed definition
- Speed formula
- Average speed formula
A
- Rate of change if distance
- V= x/t
- Average speed = Total distance/total time
6
Q
Instantaneous speed definition
A
Total distance per infinitesimal (very small) time interval
7
Q
- Average velocity definition
2. Formula
A
- Rate of change of displacement
2. Average velocity = total displacement/ total time
8

9
Q
- Acceleration definition
- Formula
- Unit
A
- The rate of change in velocity
- Acceleration = velocity/ time
- m.s^-2
