This is an energy transfer practical for bouncing balls and a homework sheet on working out the friction force for a rollercoaster.
The lesson - Bouncing balls practical. Worksheet and simple instructions for a lesson on bouncing balls to think about the energy transfers and calculating the efficiency of the bounce.
Homework (or classwork) sheet on calculating gravitational potential energy, kinetic energy and work done due to friction. Finishing with calculating the average frictional force.
Both the classwork and homework sheets have model answers provided.
Please rate this and I hope you enjoy the lesson!
