Bob tries to ride his bike with flat tires. It is hard to do. Why is it easier to ride a bike with inflated tires? Make sure you use at least one of the forces in your response.

Inflating tires reduces the amount of friction.

As Bob turns sharply on a roller coaster, his body continues to move in a straight line. The roller coaster's harness keeps him from flying out. What is the reason his body keeps moving in a straight line?

Bob has inertia. His body wants to keep moving in the same speed and direction that it is already going.
