Friction
... • Sliding or kinetic friction: frictional force between objects that are sliding with respect to one another. • Once enough force has been applied to the object to overcome static friction and get the object to move, the friction changes to sliding (or kinetic) friction. • Sliding (kinetic) friction ...

... Assume that the object is traveling at the critical velocity, so that it just barely touches the track at the top of the loop. Find the sum of the forces acting on the object at the top of the loop. Express your answer in terms of given quantities and g, the magnitude of the accleration due to gravi ...

... What is a force? “When a net force acts on a body, the body accelerates in the direction of the net force. The acceleration is directly proportional to the force, and inversely proportional to the body’s mass” Often you literally feel them: when an object presses on you, your biology can sense it U ...
