Question
A car accelerates from rest at a rate of 3 m/s² for 5 seconds. Calculate the change in velocity of the car Explain your answer using Acceleration and acceleration.
Answer
15 m/s
Explanation
A strong answer should address calculate change in velocity from acceleration and time directly. Use the context of Acceleration 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
Common Mistake in Acceleration Calculations
Students often confuse change in velocity with acceleration, leading to incorrect calculations.
To fix this, remember that change in velocity is the product of acceleration and time. Use the formula: change in velocity = acceleration x time.
