If an object on a horizontal platform is moving at a constant velocity of 10m/s, and then begins to accelerate, what happens to the force of friction?
Some people are telling me that the force of friction decreases and therefore the object accelerates...
HOWEVEr..
force of friction =...
How do you find the heat produced from the frictional force between two objects. For example, a person roller skating on a rink or a car going at 100m/s.
