BRIDGEPORT, W. Va (WDTV) - For this Kate's Corner is it best to do it outside or some where where it is okay to potentially spill a bit of water.
Here's what you'll need:
- A bucket half filled with water
All you have to do is take your bucket that is half filled with water and spin it in a circle around. Keep spinning until your arm gets tired. Be careful when stopping. Slowly stop spinning to a void spilling any water.
So why does the water not dump out? That is thanks to something called centripetal force. This is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.
The water's inertia wants to continue traveling in a straight path but the gravity causes it to fall in a downward path towards the earth. However, while the water is falling downward, the bucket is falling with it and catching the water. The centripetal force keeps the bucket and the water on its path of motion and gives the illusion that it is pulling the water away from the center.
This type of force can also be seen on roller coasters or by satellites in orbit around a planet.
