Study Notes
Units of Speed
- The SI unit of speed is meter per second (m/s)
Calculating Average Speed
- The formula to calculate average speed is: average speed = total distance / total time taken
Types of Motion
- Non-uniform motion is exemplified by a car traveling around a circular track, as its velocity changes constantly due to the change in direction
