Coin Flick Force And Motion Experiment
In this fun and easy force and motion science experiment for kids, we’re going to explore inertia and friction by seeing if we can flick a coin from the bottom of a stack of coins.
- 12 nickels
- Stack 11 of the nickels on top of each other on a smooth table.
- Place the remaining nickel on the table about one inch away from the stack.
- Use your middle finger to flick the coin at the bottom coin in the stack. If all goes well, the bottom coin should fly out from the stack without knocking the stack of coins over.
- A body at rest tends to stay at rest.
How it Works:
When the bottom coin was struck, the force overcame inertia and knocked the bottom coin away. The remaining coins will simply try to stay at rest and the stack of coins will drop down due to gravity when the bottom coin gets knocked away.
Make This A Science Project:
Try different types of stacks of coins. Try mixing different types of coins in the stack. Try safely using a butter knife to knock away the bottom coin.
