Patterns of Motion & Friction

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is the purpose of reducing friction in a bowling alley?

Back

Reducing friction helps the bowling ball roll smoothly down the lane.

Front

What happens when two surfaces rub against each other?

Back

They produce heat due to friction.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, like how it pulls us toward the Earth.

Front

What is a pendulum?

Back

A pendulum is a weight hung from a fixed point that swings back and forth.

Front

How does the length of a pendulum affect its motion?

Back

The length of a pendulum affects how fast it swings; shorter pendulums swing faster.

Front

What are patterns of motion?

Back

Patterns of motion are regular and predictable movements of objects.

Front

How can we use patterns of motion?

Back

We can use patterns of motion to make predictions about how objects will move.

Front

What is an example of a surface that reduces friction?

Back

Oil is an example of a substance that reduces friction.

Front

What is produced when friction occurs?

Back

Heat is produced when friction occurs between two surfaces.
