4. Describe all the forces acting on a child riding a horse on a merry-go-round. Which of these forces provides the centripetal acceleration of the child?


5. A bucket of water can be whirled in a vertical circle without the water spilling out, even at the top of the circle when the bucket is upside down. Explain.

    4. Centrifugal force is the force spining the child out, (centrifuge from chem makes all the massive stuff go to the outside) F friction from the horse causes the centripital acceleration. also there is grav/ normal force (from the horse)

    5. Centrifugal force is greater then gravity and the centripetal force

    we are learning the same stuff as you, its nice knowing we aren't falling behind or anything.

    btw: centripetal acceleration is the friction force holding the things in when it spins around.

    No. Centrifugal force does NOT exist, it is simply a laymans term for the fact that due to Newton's laws your body wants to go in a straight line but you are on a circular path. There is friction, gravity, and normal thats it.
