Friction and Air Resistance

Open Ended

Why is it important to understand the forces of friction and gravity in our daily lives?

Multiple Choice

Which of the following is an example of a force acting on an object?

• Pushing a door

• Watching TV

• Sleeping

• Reading a book

Multiple Choice

What force pulls objects toward the center of the Earth and acts the same on all objects (ignoring air resistance)?

• Gravity

• Friction

• Magnetism

• Electricity

Multiple Choice

Which surface would likely have more friction, making it harder to move: ice or concrete?

• Ice

• Concrete

• Both have the same friction

• Neither has friction

Multiple Select

Which of the following are types of friction?

• Sliding friction

• Rolling friction

• Air resistance

• Magnetic friction

Open Ended

Describe a situation in your daily life where you have experienced friction or air resistance. What happened and how did it affect your movement?

Multiple Choice

In the Sliding Surfaces Lab, which material would likely result in the object sliding the farthest distance?

• Carpet

• Tile

• Plastic

• Cardboard

Open Ended

Give a real-life example where friction is important.

What is friction?

Open Ended

Drop two objects (coffee filter vs. ball). Why do they fall differently?

Open Ended

Which object had more air resistance? Larger surface → slower fall.

Multiple Choice

Which of the following statements best explains the relationship between friction, air resistance, and gravity as described in the lesson?

• Friction and air resistance both resist motion, while gravity pulls objects downward.

• Friction pulls objects downward, while air resistance and gravity resist motion.

• Gravity resists motion, while friction and air resistance pull objects downward.

• Air resistance pulls objects upward, while friction and gravity resist motion.

Open Ended

Describe a real-life situation where both gravity and friction act on an object, and explain how each force affects the object's motion.
