Study Notes
Speed
- Speed is the distance traveled by an object divided by the time taken to travel that distance.
- Speed is measured in meters per second (m/s).
- Speed = distance / time
Velocity
- Velocity is the speed of an object in a particular direction.
- Velocity is different from speed because velocity takes direction into account.
- If two birds leave the same tree at the same time and fly at the same speed for the same amount of time, they won't end up in the same place because they might fly in different directions.
Acceleration
- Acceleration is the rate at which velocity changes.
- Acceleration occurs when speed increases, decreases, or when direction changes.
- An object with constant velocity has zero acceleration.
- Acceleration = rate of change of velocity
