Evaluate uncertainty in kinematics measurements

Paper 1, Paper 2 5 marks Difficulty 3

Evaluate percentage uncertainty in distance data

In a lift motion log, a measured distance is \((32\pm0.22)\,\text{m}\). Calculate the percentage uncertainty in the distance. State the method before entering the value. Enter the numerical result and choose the interpretation that matches the physics meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
