What part of a car increases friction?

Back

Tires increase friction in a car.

Front

Which of these pendulums do you predict will have the fastest motion?

Back

The shortest pendulum will have the fastest motion.

Front

What do you predict about the pattern of motion for Izzy and Zoe's pendulums?

Back

The long pendulum will swing slowest.

Front

What is the purpose of the air in air hockey?

Back

The air in air hockey reduces friction.

Front

Define friction in the context of motion.

Back

Friction is the resistance that one surface or object encounters when moving over another.

Front

What factors affect the amount of friction between two surfaces?

Back

The amount of friction is affected by the types of surfaces in contact and the force pressing them together.

Front

Explain how friction can be both beneficial and detrimental.

Back

Friction is beneficial for providing grip and control, but it can be detrimental by causing wear and heat loss.

Front

What is the relationship between the length of a pendulum and its period of swing?

Back

The longer the pendulum, the longer its period of swing; shorter pendulums swing faster.

Front

How does surface texture influence friction?

Back

Rougher surfaces increase friction, while smoother surfaces decrease it.
