Egg experiment to demonstrate inertia
A simple and effective practical demonstration of inertia using a spinning raw egg.
When the egg is spun its contents also spins. Momentarily stopping the egg does not stop its contents from spinning. On release the egg begins to spin again. The contents of the egg resist any change in its motion.
This could be developed by discussing how we utilise inertia, for example a flywheel on a bus to save energy.
Key words: inertia, spinning.
NC: Newtons laws of motion. Understand what factors affect the moment of inertia.
