Question
A car accelerates from a speed of 10 m/s to 30 m/s in 5 seconds. Calculate the acceleration of the car Explain your answer using Acceleration and acceleration.
Answer
4 m/s²
Explanation
A strong answer should address calculate acceleration from change in velocity 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
Misunderstanding Acceleration Calculation
Students often confuse acceleration with velocity and incorrectly use the formula for velocity instead of the correct formula for acceleration.
To calculate acceleration, remember to use the formula: acceleration = change in velocity / time taken. Ensure you clearly identify the change in velocity and the time interval.
