Patterns of Motion & Friction

Front

What is a pattern of motion?

Back

A pattern of motion is a repeated movement that can be observed, such as swinging, rolling, or sliding.

Front

What happens to a pendulum with a longer string?

Back

A pendulum with a longer string swings slower than one with a shorter string.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact.

Front

How does air affect motion in air hockey?

Back

Air reduces friction, allowing the puck to glide smoothly across the table.

Front

What is produced when two surfaces rub against each other?

Back

Heat is produced when two surfaces rub against each other due to friction.

Front

What can patterns of motion help us do?

Back

Patterns of motion can help us make predictions about how objects will move.

Front

What part of a car is designed to increase friction?

Back

The tires of a car are designed to increase friction for better grip on the road.

Front

What is an example of a pattern of motion?

Back

An example of a pattern of motion is a swing moving back and forth.

Front

What effect does increasing friction have on motion?

Back

Increasing friction slows down the motion of an object.

Front

What is the role of friction in everyday life?

Back

Friction helps us walk without slipping and allows cars to stop.
