If you're interested in object motion and like taking mechanical objects apart to see how they work, then it sounds like you'd be interested in applied mechanics. Check out one of the Project Ideas below and you could find the science fair project you're looking for. Here are a few of the topics that are covered:
Rubber Bands for Energy
If you've ever been shot with a rubber band then you know it has energy in it, enough energy to smack you in the arm and cause a sting! How can the energy of a rubber band be put to work? In this experiment you will find out how the stretching of a rubber band affects the amount of energy that springs out of it.

Soda Straw Robot Simulator
Robots come in many shapes and sizes. Everything from the Mars Rover to a toy dinosaur is a well planned machine designed to suit its purpose. In this experiment you will test different robot designs with an online simulator. How will each robot design respond?

Take the Sally Ride Science TOYchallenge!
Doesn't working as a toy designer sound like the coolest job ever? You might be surprised at how much brain power it really takes. In this science fair project, you'll get to try your hand at combining fun with function. You and your small team will get to design your own entry that teaches, demonstrates, or tests a scientific concept for the Sally Ride TOYchallenge!

Air Pressure and Rolling Resistance
*
How does the air pressure in a tire affect the rolling resistance of a bicycle or wheelbarrow? Do you need more or less effort to move the bicycle (or wheelbarrow) as the air pressure is changed?...

Physics of Vibrations
*
Tennis racquets, baseball bats and golf clubs all vibrate when they hit the ball. You can often feel it in your hands, particularly if you "mis-hit" the ball. You can find the point(s) on your...

Domino Theory
*
Have you ever set up a line of dominoes and watched them fall? If you wanted to make your line of dominoes fall faster, do you think you should set the dominoes up with more or less space between...

Knock Your Blocks Off: The Mechanics of Carnival Games
"Hey kids, step right up! Toss this ball and win a prize!" shouts the carny barker. Sounds easy enough—until you try it. Why are those "simple" games at the fairs, carnivals, and boardwalks so hard? Is it really lack of skill or coordination or do those concessionaires use some basic laws of science to help them set up the games in their favor? This science fair project can help you find out for yourself.

Effect of Friction on Objects in Motion
The funny thing about friction is that you couldn't get anywhere without it, yet it still acts to slow you down as you're getting there. Here is an easy project to measure the effects of friction.

Jack and Jill Went Up a Hill and Came Biking Down After: Choosing the Best Gear Ratio for Speed
Are you a budding Lance Armstrong or Greg LeMond? Are you into cycling and speed? Then this is the science fair project for you! In this science fair project, you will determine the best gear ratio for your bike, to get the highest speed after a curve and onto a straightaway. You will learn a lot about applied mechanics and gears, all while having fun riding your bike.

Mix It Up: Transferring Heat by Convection in a Tank
Big, puffy, cotton-like clouds, and the bubbles in a pot of boiling water may not seem like they have much in common, but they do—both are formed by a heat-transfer process called
convection. Warmed gases and liquids rise, while cooler ones fall, creating currents and mixing things up. Whether making processed foods in a factory or making plastic or metal parts, knowing how to mix up a big tank of hot and cold liquids or gases quickly is important. Engineers must rely on experimentation to get the best mixing method, as will you when you build a mini mixing tank in this engineering science fair project.
