Question

Name the three types of friction.​

Answer 1

Explanation:

three types of friction: rolling friction, starting friction, and sliding friction.

Answer 2

Answer:

FRICTION

• Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

TYPES OF FRICTION

There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases.

CAUSES OF FRICTION

• The causes of this resistive force are molecular adhesion, surface roughness, and deformations. Adhesion is the molecular force resulting when two materials are brought into close contact with each other.

EXAMPLES OF FRICTION

1. Rubbing both hands together to create heat.
2. A sled sliding across snow or ice.
3. A washing machine pushed along a floor.
4. A person sliding down a slide is an example of sliding friction.
5. An iron being pushed across material.
