Define friction in your own words.

What is the force that opposes motion called?
It starts with 'F' and keeps things from sliding easily.
True or False: Static friction acts on moving objects.
Think about the term 'static' refers to.
A 10 kg box is pushed across a surface with a coefficient of kinetic friction of 0.3. Calculate the frictional force acting on the box.
Don't forget to calculate the normal force first!
Explain how to reduce friction for a bicycle. Consider factors involved in reducing the static and rolling friction.
Think about how professional bikes are designed for speed.
