How many possible directions are there for the frictional force?
Physicists categorize the frictional force according to the relative motion between the two surfaces. What are some of the categories?
One category of frictional forces is the static frictional force. What is the relative motion between the surfaces for this category? Describe a theory of static frictional forces.
Another category of frictional forces is the kinetic frictional force. What is the relative motion between the surfaces for this category? Describe a theory of kinetic frictional forces.

3. Solve for frictional force in part A and the net force in Part B . Write your final answers for parts A and B rounded to 3 significant digits. a. A 2.14 kg block is sliding along a rough horizontal surface, and the only unbalanced force acting on the block is a constant frictional force. Suppose the block is moving at speed 88.8 m/s at t = 0, and after 38.9 seconds it comes to rest. Find the magnitude...

Since the floor is rough, it exerts both a normal force N1 and a frictional force f1 on the ladder. However, since the wall is frictionless, it exerts only a normal force N2 on the ladder. The ladder has a length of L = 4.1 m, a weight of WL = 58.5 N, and rests against the wall a distance d = 3.75 m above the floor. If a person with a mass of m = 90 kg is standing...

Gravity is a long-range force proportional to the masses of the interacting bodies. Physicists have long searched

Gravity is a long-range force proportional to the masses of the interacting bodies. Physicists have long searched to see if there might be a long-range force that is proportional to baryon number. Think about the composition of atoms and propose a “thought experiment” that could detect such a force.

A wheel slows from 500 rad/s to rest in 80.0 seconds due to a frictional force that is applied to the outer rim of the wheel. Treat the wheel as a solid disk with radius R = 12.0 cm and mass M = 350 grams. What is the magnitude of the frictional force that causes the wheel to slow to a stop?

According to Newton's third law, for every force there is always a reaction force of equal magnitude and opposite direction. In each of the examples below, identify an action-reaction pair of forces. (a) A tennis racket hits a tennis ball, exerting a force on the ball. (Select all that apply.) the force exerted by the tennis ball on the racket the force felt in the player's arm at time of contact the force the tennis racket exerts on the tennis...
