Study Notes
Acceleration
- Rate of change of velocity
- Change in acceleration: Vf - Vi (Final velocity - Initial velocity)
- Formula: Vf -- Vi / t (Final velocity - Initial velocity over time)
Velocity
- How fast something moves
- Change in velocity: Vf -- Vi (Final velocity - Initial velocity)
Displacement
- Distance with a direction
- Formula: Velocity x Time
- Measured in meters (m)
Speed
- How fast something moves without direction
- Measured in m/s
- Formula: Total distance / Total time
- Average speed does not require a conversion to m/s
- Average speed is measured in m/s
- Time is measured in seconds (s)
Distance
- How far something moves
- Formula: Speed x Time
- Measured in meters (m)
Formulas
- Distance = Velocity x Time
- Acceleration = Vf -- Vi / Time
- Average speed = Total distance / Total time
- Displacement = Velocity x Time
Summary of Conversions
- Distance: m
- Speed: m/s
- Velocity: m/s
- Acceleration = m/s2
- Time = s
