Common mistake

Average vs Instantaneous Speed Confusion

Students often confuse average speed with instantaneous speed, thinking they are the same concept.

To fix this, remember that average speed is calculated over a total distance and time, while instantaneous speed is the speed at a specific moment. Practice identifying examples of each in different scenarios.
