Energy > kinetic energy (KE)

Simple demonstrations to introduce the concept of kinetic (motion) energy.

Moving matter can carry energy from one energy store to another. In Demonstration A, elastic bands store energy. Demonstration B introduces energy stored in a magnetic field.

The simple pendulum used as a stimulus to discuss energy transfers.

Roll a ball on a curved track to explain Galileo's idea, which in turn led to Newton's First Law of Motion.

Comparing the energy stored by two rubber bands.

To move along a horizontal plane there is no net transfer of energy from potential energy to kinetic (motion) energy.

When a pendulum is displaced, it gains gravitational potential energy due to its increased height. When subsequently released, this energy becomes transferred to kinetic energy. This datalogging experiment explores the relationship between these changes of energy.

Friction spoils the downhill and uphill experiment of a rolling ball on a curved track. This is Galileo's almost frictionless version of it.
