Is the following statement true? CentriFgal Force? Is the following statement true? 6 January 2K + 5 http://teacher.scholastic.com/products/instructor/Aug04_playground.htm

Stronger Than Gravity SCIENCE CONCEPT: Is there any force that can defy gravity? Actually, yes! Centrifugal force pushes objects that are moving in a circular path towards the outside of that path, keeping them moving in a circle.   TRY THIS: To demonstrate centrifugal force for students, place a tennis ball (or other light, harmless object) into a plastic bucket. Ask students what will happen when you turn the bucket upside down. The ball will fall out, of course. Why? Gravity! Now say you will show them a force that can actually defy gravity, called centrifugal force. Have students each take turns holding the bucket and swinging it around in a vertical circle so that the object stays in on each swing. Explain that this force is the same force they feel pushing them to one side when riding in a car or on a bike that takes a sharp curve.

That’s all folks!
