Physics Summary

So as you can see, there are many different factors that affect physics in bicycles. It was hard to figure out what parts of the physics I wanted to cover.  So just a little review:

• The Handlebars are a very important part of the bicycle making it able to be steered by the rider.  The physics involved are motion and steering angle.
• The gears are a simple machine (wheels and axles) that allow the bike to go at different speeds.  They also have motion involved along with torque and speed.
• The tires make the bike move and help with steering the bicycle.  They also make the bike turn.  Physics in tires include torque, motion, and friction.
• Internal forces and external forces are applied to bicycles through gravity, friction, the rider, brakes, steering, etc.
