What type of force occurs when two surfaces slide past each other?
Which of the following is not true about Kinetic friction?
If a block at rest on an inclined plane begins to slide when the incline angle is increased to 30 degrees, what is the coefficient of static friction between the block and the plane?
Which of these forces is a contact force?
A shopping cart has three wheels that roll on frictionless bearings, but one of the side wheels A (left) or B (right) has significant friction. When a force is applied to the handle as shown, the center of mass of the cart speeds up and the cart turns to the left. Which wheel has friction, and is the friction gre...
There is a 10 kg block resting on the ground with a coefficient of static friction of 0.8 and a coefficient of kinetic friction of 0.3. The block is pulled horizontally by a 55 N force but stays at rest. How much friction acts on the block?
In what scenario might a physics student discover that Newton's third law does not always predict equal and opposite contact forces?

A skater initially at rest pushes off from another stationary skater causing both skaters move apart; if their masses are unequal, how do their final velocities compare?
What impact does doubling the battery voltage have on the current through a resistor in a simple series circuit assuming resistance stays constant?
