Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about moments (GCSE and Key Stage 3)
Moments are an exciting area of Physics. They provide students with an understanding of every day experiences such as see-saws,using spanners, cranes and opening doors. It is best to refer to moments as clockwise and anticlockwise rather than moments on the left and right. This is a great video to demonstrate how distance and force affect the size of the moment. You can get students to experience this effect in the classroom by getting them to open doors at various distances from the hinge (pivot); they will be able to feel the difference in the force required to open the door.
Levers and moments: work done = force x distance
GCSE worksheet to help students understand levers and moments. Students work in small groups to work through some thinking problems about levers, moments and machines. (PDF)
This fantastic film explains the power of the mighty lever. How long would a lever have to be for a person to lift a smart car? Or for the same person to lift a 2.5 tonne truck? It’s a great example of how a simple machine can achieve something incredible. This second clip introduces input work and output work through the relationship, work done = force x distance and helps students to understand the trade-off between force and distance.
