Question

Which statements describe friction? Select four options.

It results from microscopic bumps and ridges.
It causes a change in motion.
It occurs in the same direction as the push force.
It is opposite to the direction of the motion.
It is parallel to the surfaces that rub together.

Answer 1

It results from microscopic bumps and ridges

It causes a change in motion

It is opposite to the direction of the motion.

It is parallel to the surfaces that rub together.

Step-by-step explanation:

Answer 2

Option (D) &(E)

It is opposite to the direction of the motion and it is parallel to the surfaces that rub together

Step-by-step explanation:

One of the simplest features of friction is that it is parallel to the inter-system touch layer and always in a position which contradicts the system's movement or attempted motion related to each other.

When two structures are in contact with each other, so kinetic friction takes place between them. For instance, friction slows down a slipping hockey puck on ice. Yet static friction will work between them when objects are at rest; static friction will be typically greater than kinetic friction between the bodies.
