3. Here is a problem that beautifully illustrates why we want this new approach. Problem: A mass of 3 kg is placed on a 60° that has a coefficient of 0.2. (Since the mass will be moving this is kinetic friction.) What is the resulting acceleration of the mass? The mass will then travel down the incline for 0.5 m until it reaches the bottom of the incline. How fast will the mass be traveling at the bottom of the incline? The mass will then slide across the floor (which is level). How far will it slide before coming to rest?

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
