How does accelerating an object affect the force of friction?

Click For Summary
When an object on a horizontal platform transitions from constant velocity to acceleration, the force of friction remains unchanged. This is because the force of friction is determined by the coefficient of friction and the normal force, both of which do not vary in this scenario. The coefficient of friction is constant for the materials involved, and the normal force stays the same on a horizontal surface. Therefore, the force of friction does not decrease as the object accelerates. The discussion confirms that, under standard kinetic friction conditions, the force of friction remains constant during acceleration.

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 = 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?

You are correct. (At least within the standard model of kinetic friction.)
 

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
