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 term for the force that opposes motion?

Back

Friction is the force that opposes motion.

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 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 shortest pendulum's motion compared to longer ones?

Back

The shortest pendulum swings the fastest.

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 a pattern of motion?

Back

A pattern of motion is a repeated movement that can be observed and predicted.

Front

What is viscosity?

Back

Viscosity is a measure of a fluid's resistance to flow, not to be confused with friction.
