- Motion
- Distance-Time graphs
- Stationary-horizontal straight line
- Moving at a constant speed - straight line at a gradient
- Gradient of line represents speed
- Speed in m/s = distance travelled (m) / time taken (s)
- Velocity & accelleration
- Velocity is speed in a given direction
- Acceleration is change in velocity per second. (m/s^2)
- Acceleration = change in velocity / time taken
- Deceleration is change in velocity when an object slows down
- Velocity-time graphs
- Horizontal line = 0 acceleration
- Gradient is the acceleration
- Area under line is the distance travelled
