Patterns of Motion & Friction

Front

What is a pendulum?

Back

A pendulum is a weight hung from a fixed point that swings back and forth under the influence of gravity.

Front

What happens to the speed of a pendulum as its length increases?

Back

The longer the pendulum, the slower it swings.

Front

What is the pattern of motion for a jump rope?

Back

The jump rope moves in a circular pattern around the person jumping.

Front

What is friction?

Back

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

Front

How does friction affect motion?

Back

Friction slows down the motion of objects.

Front

What is the fastest swinging pendulum?

Back

The shortest pendulum swings the fastest.

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 the term for the force that opposes motion?

Back

The term is friction.

Front

What is an example of a circular motion?

Back

The motion of a jump rope as it swings around.

Front

What is the relationship between length and speed in pendulums?

Back

Longer pendulums swing slower, while shorter pendulums swing faster.
