Coach's note
Your calculations are moving forward
You are selecting the right equations and showing a clear method. The next gain is making every final answer exam-ready.
- Acceleration — Your method was correct in two recent Forces questions.
- Units — m/s and m/s² are still being mixed in final answers.
Write the unit beside the answer before moving to the next part.
A short PhysicsUK Solve task should turn this into a reliable habit.
Latest marks & feedback
PhysicsUK Exam Studio: Acceleration calculation
What worked: Correct change in velocity and division by time.
Improve: Acceleration needs the unit m/s², not m/s.
View full feedbackThings to watch
Acceleration units
Keep m/s for velocity separate from m/s² for acceleration.
