Patterns of Motion & Friction

Front

What is the primary factor that causes pendulums to form neat patterns?

Back

The different lengths of the strings.

Front

What component of a car is designed to increase friction for better traction?

Back

Tires.

Front

What substance is commonly used to coat bowling alley lanes to reduce friction?

Back

Oil.

Front

What term describes the resistance to motion between two surfaces?

Back

Friction.

Front

How can you describe the motion pattern of a jump rope being swung?

Back

It moves in a circular pattern around the person swinging it.

Front

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

Back

Longer pendulums have longer periods, meaning they swing more slowly.

Front

What effect does increasing the surface area of contact have on friction?

Back

It generally increases friction, but the effect can vary depending on the materials.

Front

What is the role of lubricants in reducing friction?

Back

Lubricants create a thin layer between surfaces, reducing direct contact and thus friction.

Front

How does the weight of an object affect the frictional force acting on it?

Back

Increased weight typically increases the frictional force, as friction is proportional to the normal force.

Front

What is kinetic friction?

Back

Kinetic friction is the frictional force acting between moving surfaces.
