A block is at rest on a rough horizontal surface. A force is applied to the block. If the applied force is less than the maximum static friction force, what is the friction force acting on the block?

A car is traveling on a flat, circular track at a constant speed. What force provides the necessary centripetal force for the car to maintain its circular motion?

Two blocks, one made of wood and one made of steel, are sliding across a horizontal steel surface. Both blocks have the same mass and initial velocity. Which block will likely stop in a shorter distance?

A box with a weight of $W$ is pushed across a horizontal floor at a constant speed with a force $F$. The coefficient of kinetic friction between the box and the floor is $\mu$. What is the magnitude of the friction force acting on the box?

A heavy box is sitting on the floor. Which of the following will NOT increase the force of friction between the box and the floor?

An object is sliding down an inclined plane with friction. If the angle of the incline is increased, what happens to the friction force acting on the object?
