Patterns of Motion & Friction

Front

What is motion?

Back

Motion is the change in position of an object over time.

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?

Back

The length of the pendulum affects its speed; shorter pendulums swing faster.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it comes into contact with another surface.

Front

What are some examples of friction?

Back

Examples of friction include rubbing your hands together, sliding a book across a table, or walking on the ground.

Front

How can friction be reduced?

Back

Friction can be reduced by using lubricants like oil or by using smoother surfaces.

Front

What is the purpose of oil on a bowling alley lane?

Back

Oil is used on bowling lanes to reduce friction, allowing the bowling ball to roll smoothly.

Front

What is a circular motion?

Back

Circular motion is the movement of an object in a circular path, like a jump rope being swung around.

Front

What is the effect of air in air hockey?

Back

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

Front

What is the relationship between length and speed in pendulums?

Back

In pendulums, shorter lengths result in faster swings, while longer lengths result in slower swings.
