Question
A car accelerates from a speed of 10 m/s to 25 m/s in 5 seconds. Calculate the acceleration of the car Explain your answer using Acceleration and acceleration.
Answer
The acceleration of the car is 3 m/s².
Explanation
A strong answer should address use the equation acceleration = change in velocity divided by time taken 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 the formula for acceleration, mistakenly using distance instead of change in velocity.
Remember that acceleration is defined as the change in velocity over time. Use the correct formula: acceleration = change in velocity / time taken.
