8.1 Lesson 9 QUIZ

What is friction?

• A force that resists motion between surfaces in contact

• A force that transfers energy between objects and particles in the air

• A force that pushes objects in the direction of their motion

Which force is responsible for making it harder to slide on a carpet compared to a smooth floor?

• Friction

• Air resistance

• Gravity

• Magnetism

What is air resistance?

• A force that pushes objects in the direction of their motion

• A force that resists motion between surfaces in contact

• A force that slows down objects moving through the air

• A force that increases the temperature of objects

What happens when objects slide over each other?

• Energy is transferred, resulting in a change in shape

• Energy is transferred, resulting in a temperature change

• Energy is transferred, resulting in a change in color

What is the role of friction and air resistance when objects collide?

• They increase the speed of the objects

• They decrease the speed of the objects

• They change the direction of the objects

• They have no effect on the speed of the objects
