Patterns of Motion & Friction

Front

What is a pattern of motion?

Back

A pattern of motion is a repeated way in which an object moves, such as swinging, rolling, or spinning.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, making it slow down or stop.

Front

What happens to a pendulum when the string is longer?

Back

A longer string causes the pendulum to swing more slowly.

Front

What happens to a pendulum when the string is shorter?

Back

A shorter string causes the pendulum to swing faster.

Front

What role does gravity play in motion?

Back

Gravity pulls objects down towards the Earth, affecting how they move.

Front

How does friction affect motion?

Back

Friction can slow down or stop moving objects, like when you slide on the ground.

Front

What is an example of circular motion?

Back

An example of circular motion is a jump rope moving around a person.

Front

What is an example of back-and-forth motion?

Back

An example of back-and-forth motion is a swing moving in a straight line.

Front

What is the purpose of air in air hockey?

Back

The air reduces friction, allowing the puck to glide easily across the table.

Front

What is the relationship between the length of a pendulum and its speed?

Back

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