Velocity - Distance - Time
- Speed (Velocity) is a change in distance per unit time. SI unit: meters per second (m/s or (ms-1)
- Distance is a length. SI unit: meters (m)
- Time is needed for things to change. SI unit: second (s)

Acceleration - Velocity - Time
- Acceleration is a change of speed (velocity) per unit time. SI unit: meters per second per second or meters per second squared (ms-2)
- Speed (Velocity) is a change in distance per unit time. SI unit: meters per second (m/s or ms-1)
- Time is needed for things to change. SI unit: second (s)
Optimisation of Trebuchet:
- The length of the payload arm should be 3.75 times longer than the counterweight arm.
- The length of the sling should be the same length as thepayload arm.
- The initial angle between the counterweight arm and the support should be 45 degrees at launch.
- The counterweight needs to be 133 times as heavy as your intended projectile.
