Pulleys

Connected particles in motion

In this practical activity two objects are connected via a string that passes over a pulley; then they are released from rest. Can you use your knowledge of mechanics to predict the time taken for the heavier object to fall to the ground and the greatest height reached by the lighter object? Do the calculations and then check your predictions.

This practical is designed to be easily set up and carried out in a maths classroom using simple equipment. It will help students to understand the mechanics topic of kinematics and constant acceleration equations in AS and A level Mathematics.

The video features the equipment needed and the practical procedure. The teacher notes contain additional guidance on carrying out the activity, sample calculations and suggested points for discussion, as well as an indication of some relevant real-life applications.
