The learning connection

Hands-on activities engage students and enhance understanding. By creating their own pulleys, students can see physics in action, making learning memorable.

Try it with your learner

1. Tie one end of the string to the small weight. 2. Thread the other end of the string through the pulley and secure it to the support stand. 3. Lift the weight by pulling down on the free end of the string. 4. Observe how much easier it is to lift the weight with the pulley. 5. Try lifting the weight without the pulley for comparison. 6.
