Circular motion is a little different from straight-line motion in a few different ways. Objects that move in circles are roller coasters in a loop, satellites in orbit, DVDs spinning in a player, kids on a merry go round, solar systems rotating in the galaxy, making a left turn in your car, water through a coiled hose, and so much more.
For any object that goes in a circle (or you can approximate it to a circle), you'll want to use this approach when solving problems. You can feel the effect of circular motion if you've ever been in a car that suddenly turns right or left. You feel a push to the opposite side, right? If you are going fast enough and you take the turn hard enough, you can actually get slammed against the door. So my question to you is: who pushed you? That's what this section is all about.

Be sure to take out a notebook and copy down each example problem right along with me so you take good notes as you go along. It's a totally different experience when you are actively involved by writing down and working through each problem rather than passively sitting back and watching.
