Patterns of Motion and Friction

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

What affects the speed of a pendulum's swing?

Back

The length of the string affects the speed; shorter strings swing faster than longer ones.

Front

What is friction?

Back

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

Front

What happens to a pendulum when there is more friction?

Back

More friction slows down the pendulum's swing.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward the Earth.

Front

How does gravity affect a pendulum?

Back

Gravity pulls the pendulum down, causing it to swing back and forth.

Front

What is produced when two surfaces rub against each other?

Back

Heat is produced when two surfaces rub against each other.

Front

What is the relationship between string length and pendulum speed?

Back

The shorter the string, the faster the pendulum swings.

Front

What is resistance to motion called?

Back

Resistance to motion is called friction.

Front

What causes pendulums to form neat patterns?

Back

Different lengths of string cause pendulums to form neat patterns.
