- P2 1.2 Velocity and acceleration
- Velocity is speed in a given direction.
- Acceleration is change of velocity per second.
- The unit of acceleration is the meter per second squared (m/s2).
- Acceleration (m/s2) = change in velocity (m/s(see red bubble)) / time taken (s)
- Deceleration is the change of velocity per second when an object slows down.
- initial velocity = u final velocity = v time = t acceleration = v-u/t
