How does accelerating an object affect the force of friction?
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...
force of friction = Coefficient of friction ( Normal Force)
Going from constant velocity to acceleration doesn't affect any of the variables in that equation..
Coefficient of friction is a constant that depends on the two materials, which remain constant, and Normal force is the same because the object is still on a horizontal platform. Therefore, going from constant velocity to uniform acceleration should not affect the force of friction should remain constant...Am I wrong?
