WebMar 26, 2016 · Friction is a force, and from physics, you know that forces can change an object's speed or direction. The force of friction from dry pavement on your car's tires is much greater than the force of friction from snow or ice. Why? Because ice produces much less friction with your car's tires than the dry pavement does. Webno, we assume that friction is given by the equation (coefficient of friction)*normal force. That doesn't vary. also the formula works as long as you use average force. Doesn't have to be constant ( 6 votes) Hafsa Kaja Moinudeen 7 years ago How does energy change into heat?
