<li><p>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?</p></li>
<li><p>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.</p></li>

<ol>
<li><p>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)</p></li>
<li><p>Centrifugal force is greater then gravity and the centripetal force</p></li>
</ol>
<p>we are learning the same stuff as you, its nice knowing we aren't falling behind or anything.</p>
<p>btw: centripetal acceleration is the friction force holding the things in when it spins around.</p>
<p>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.</p>
