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 does it mean to reduce friction?

Back

To reduce friction means to make it easier for objects to slide past each other, often by using a lubricant or smooth surface.

Front

What is a pendulum?

Back

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

Front

How does the length of a pendulum affect its motion?

Back

The length of a pendulum affects its speed; shorter pendulums swing faster than longer ones.

Front

What is the purpose of air in air hockey?

Back

The purpose of air in air hockey is to reduce friction, allowing the puck to glide smoothly across the table.

Front

What is produced by the friction of two surfaces rubbing against one another?

Back

Heat is produced by the friction of two surfaces rubbing against one another.

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 is motion?

Back

Motion is the change in position of an object over time.

Front

What is an example of a pattern of motion?

Back

An example of a pattern of motion is the regular swinging of a pendulum.

Front

What happens to a pendulum when it is longer?

Back

A longer pendulum swings more slowly compared to a shorter one.
