Patterns of Motion & Friction

Front

What causes the pendulums to form neat patterns?

Back

Different lengths of strings cause pendulums to swing in neat patterns.

Front

What is the pattern of motion of the jump rope?

Back

The jump rope moves in a circular motion around Izzy.

Front

What is the purpose of the air in air hockey?

Back

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

Front

What is produced by the friction of two surfaces rubbing against one another?

Back

Heat is produced when two surfaces rub together.

Front

What do you predict about the pattern of motion for Izzy and Zoe's pendulums?

Back

The long pendulum will swing slowest compared to the short one.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces.

Front

How does gravity affect motion?

Back

Gravity pulls objects towards the Earth, affecting their motion.

Front

What happens to a pendulum when the string is shorter?

Back

A shorter string causes the pendulum to swing faster.

Front

What is a pattern of motion?

Back

A pattern of motion is a repeated movement that follows a specific path.

Front

How can we reduce friction?

Back

We can reduce friction by using lubricants like oil or by using smoother surfaces.
