Science Friction Quiz

What is friction?

• Force that opposes motion

• Force that attracts objects

• Force that causes motion

• Force that increases speed

Name the three types of friction.

• surface friction

• fluid friction

• static friction, kinetic friction, and rolling friction

• air friction

Which type of friction occurs when an object is not moving?

• Static friction

• Kinetic friction

• Rolling friction

• Fluid friction

Which type of friction occurs when an object is in motion?

• fluid friction

• kinetic friction

• rolling friction

• static friction

What are the factors that affect friction?

• Color of the surfaces, shape of the surfaces, size of the surfaces

• Nature of surfaces, force pressing surfaces, presence of lubricants or contaminants

• Temperature, weight of the object, speed of the object

• Distance between the surfaces, time of contact, angle of the surfaces
