friction, more aerodynamic
• Which bike will be faster? Why?
Copyright © 2010 Ryan P. Murphy
 Road bike
 Light weight
 Small thin tires = less
friction, more aerodynamic
 Mountain bike
 Heavy / Durable
 Wide tire with lots of
grip to increase friction.
 Fluid friction: When an object is moving in
liquid or gas.

“Why does
a golf ball
have
dimples?”
• A golf ball has dimples to make it more air
resistant.
• A golf ball has dimples to make it less
resistant to the air.
– Thus travel further and straighter.
• A golf ball has dimples to make it less
resistant to the air.
– Thus travel further and straighter.
• A golf ball has dimples to make it less
