Question
An object travels 100 meters to the east in 5 seconds. Calculate its velocity Explain your answer using Distance, displacement, speed and velocity and speed.
Answer
The velocity of the object is 20 m/s to the east.
Explanation
A strong answer should address define velocity as speed in a given direction 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
Confusing Speed and Velocity
Students often define velocity simply as speed, without mentioning the direction.
Emphasize that velocity includes both the speed of an object and the direction in which it is moving.
