Question
A car travels 100 meters in 5 seconds. What is its average speed Explain your answer using Distance, displacement, speed and velocity and speed.
Answer
The average speed of the car is 20 meters per second.
Explanation
A strong answer should address distinguish average speed from instantaneous speed directly. Use the context of Distance, displacement, speed and velocity within Forces and motion, then state the relevant forces or motion reasoning with units where needed. The answer is correct when it names the key physics quantity, keeps speed and velocity distinct, and links the conclusion back to the approved learning objective.
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.
