Friction And Air Resistance

Front

What is friction?

Back

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

Front

What factors affect the amount of friction between two surfaces?

Back

The amount of friction depends on the roughness of the surfaces and the weight pressing them together.

Front

How can friction be increased?

Back

Friction can be increased by making surfaces rougher or increasing the weight on the surfaces.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against objects moving through the air.

Front

How does air resistance affect falling objects?

Back

Air resistance slows down falling objects, making them reach a lower terminal velocity.

Front

What is the relationship between speed and air resistance?

Back

As the speed of an object increases, air resistance also increases.

Front

Why is friction important in everyday life?

Back

Friction allows us to walk without slipping, hold objects, and stop vehicles.

Front

What happens to an object if there is no friction?

Back

Without friction, objects would slide indefinitely without stopping.

Front

How does friction affect the motion of a sliding object?

Back

Friction slows down the motion of a sliding object.

Front

What is the effect of lubricants on friction?

Back

Lubricants, like oil, reduce friction between surfaces.
