What is friction?
What are the forces of static and kinetic friction?
Static frictional force
Kinetic frictional force
A car slows gently to a stop.
A car slams on the brakes and skids to a stop.
A car accelerates gently to a higher speed.
A car "floors it" and peels out of a stop light.
A car takes a turn gently.
What is the formula for the kinetic frictional force ?
What is the formula for the static frictional force ?
What do solved examples involving the force of friction look like?
Example 1: Push the fridge
To start we'll solve for the maximum possible amount of static frictional force.
