Introduction:
-Centripetal force is basically the motion of an object in a circle, at a constant speed. It is the force directed toward the center of the circle.
-Driving Question:
What factors influence the force experienced by an object that travels on a circle at a constant speed?
-Important questions to considerate "How does this work?" and also "What keeps the water from falling down?"
Materials:
-Centripetal force board
-Glass of water ( I used medicine cups)
Safety Regulations:
If you're using a glass you should be very careful so the glass does not shatter and hurt you!
Scientific Principles:
Law of motion. According to Newtons Law of Motion- an accelerating object must be acted upon by an unbalanced force. Without centripetal force, centrifugal force will keep the object moving in a straight line once released from circular motion.
Procedure:
This is a fun and easy experiment! First you will need to gather your materials of course. Have your centripetal board ready and fill a cup or glass (basically any object that can be filled & stand on its own) and place it on the board. Next, hold the board by the rope and begin to swing the board a little to the left and right to gain motion. Then, spin it over the top of your head in one complete circle, and if done right, the water should not spill.
