What does friction do?

Back

Friction is a force that opposes motion between two surfaces that are in contact.

Front

What is gravity's role in motion?

Back

Gravity pulls objects down towards the Earth, affecting their motion.

Front

How does the length of a pendulum's string affect its swing?

Back

The length of the string determines how fast or slow the pendulum swings.

Front

What is an example of back and forth motion?

Back

A swing moving back and forth is an example of back and forth motion.
