Inertia Demonstration for Kids
What is Inertia?
Inertia is Newton’s first law of motion, which is the principle of physics which states an object at rest will stay at rest and an object in motion will stay in motion.
How to Demonstrate Inertia
Cut a stripe of paper about 2 inches wide. Loop the paper and secure it with a piece of tape, so that you have a paper circle. Balance the loop of paper on top of a film canister. I found some film canisters of Amazon. Balance the penny on top of the loop.
Put a pencil in the loop and jerk it to the side. The jerking motion should pull the paper to the side. Allowing the penny to drop into the canister below.
How is that Inertia?
In this demonstration of inertia the penny is resting on the loop. So using the principles of physics, unless the penny is touched it should not move. This is demonstrated in this activity. When you move the loop with the pencil, you are moving it so quickly that the penny stays at rest and falls into the canister (also at rest).
