Class practical: Comparing the energy stored by two rubber bands.
Demonstration: Introducing the concept of conservation of energy and a definition of the joule.
Class practical: Considering the energy stored in foodstuffs and the energy demanded by human activity.
Demonstration: Using a dynamics trolley on a steep ramp, where the energy transfer is not easily measured.
Demonstration: To move along a horizontal plane there is no net change to the way energy is stored.
Demonstration: Students ‘experience’ forces and reinforce their understanding of force and energy units.
Class practical: Measuring the gravitational potential energy transferred to kinetic (motion) energy with a dynamics trolley.
Demonstration: Collisions between trolleys that result in energy being dissipated to the surroundings.
Demonstration: An electric motor lifts a load.
