Patterns of Motion & Friction

Front

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

Back

To reduce friction between the bowling ball and the lane.

Front

How does the length of strings affect the motion of pendulums?

Back

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

Front

What is the result of friction between two surfaces?

Back

Heat is produced due to the friction of two surfaces rubbing against one another.

Front

What is the pattern of motion for a jump rope being turned?

Back

The jump rope moves in a circular motion around the person turning it.

Front

How does air in air hockey affect gameplay?

Back

Air reduces friction between the puck and the table, allowing for smoother movement.

Front

What is friction?

Back

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

Front

What factors can affect the amount of friction between two surfaces?

Back

Surface texture, material composition, and the force pressing the surfaces together.

Front

What is kinetic friction?

Back

Kinetic friction is the frictional force that opposes the motion of two surfaces sliding past each other.

Front

What is static friction?

Back

Static friction is the frictional force that prevents two surfaces from sliding past each other.

Front

How can friction be beneficial in everyday life?

Back

Friction allows us to walk without slipping, enables cars to grip the road, and helps in holding objects.
