- CHANGING SPEED
- Acceleration
- acceleration=change in speed/timetaken
- negative acceleration [m/s2] = deceleration
- Relative velocities
- velocity is a vector, both speed and direction
- two cars in opposite directions, relative velocity is the sum of individual velocities
- difference of individual velocities if going in same direction
- Circular motion
- A vehicle may go around a roundabout but is accelerating, direction of travel is changing
- Acceleration
- speed per unit time is acceleration. Speed increase=deceleration, speed decrease=deceleration
