Sliding friction, or more formally known as Dynamic Friction, or Kinetic Friction, is a resistive force that arises when one object is in contact with another object and the objects are in motion with respect to each other. Friction is called a resistive force because it always resists, or pushes against, the initial force causing the motion.
.
The factors that affect the magnitude of dynamic friction are:
- the coefficient of dynamic friction between the two bodies; and
- the magnitude of the original force responsible for the motion.
What else can I help you with?
How does the mass of sliding object affect friction?
The mass of a sliding object does not directly affect friction. Friction is primarily influenced by the nature of the surfaces in contact and the normal force pressing them together. However, in some cases, a heavier object may increase the normal force, which in turn can increase the friction force.
How does changing the type of surface area affect the sliding friction?
Changing the type of surface area can affect sliding friction because different materials have different levels of smoothness and roughness. A smoother surface will typically have less sliding friction as there is less resistance between the two surfaces. In contrast, a rougher surface will create more friction due to increased contact points and resistance.

What is the difference between static friction and sliding friction?
Sliding friction is always less than the static friction by small amount.
