Study Notes
- Speed is how fast something moves, while velocity is speed with a direction.
- Speed is measured as distance moved over time.
- Speed can be calculated using the formula: speed = distance/time.
- Speed is commonly measured in meters per second (m/s) or kilometers per hour (km/h).
- Instantaneous speed is the speed at an instant in time.
- Constant speed is when the speed does not change.
- Velocity is a vector quantity with magnitude and direction.
- Velocity uses displacement instead of distance.
- Velocity is calculated using the formula: velocity = displacement/time.
- Velocity and speed can be different if the direction changes.
