Question

An unhappy individual is trying to slide a 100 kg desk across a wood floor. He pushes with a force of 800 N but the desk does not move. One can conclude that the force of friction (relative to the applied force of 800 N) is:kg m/s2 is a valid unit for what measurement?

Answer 1

The force of friction is equal to the force applied by the unhappy individual, which is 800 N. The force of friction is equal in magnitude and opposite in direction to the applied force. The direction of friction is always opposite that of motion.

Step-by-step explanation:

The force of friction is equal to the force applied by the unhappy individual, which is 800 N, because the desk does not move. This means that the force of friction is equal in magnitude to the applied force of 800 N. Since the direction of friction is always opposite that of motion, the force of friction is also in the opposite direction of the applied force.
