Friction

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 are the four types of friction?

Back

1. Static Friction 2. Sliding Friction 3. Rolling Friction 4. Fluid Friction

Front

What is rolling friction?

Back

Rolling friction is the resistance that occurs when an object rolls over a surface, like wheels on a skateboard.

Front

What is sliding friction?

Back

Sliding friction is the resistance that occurs when two surfaces slide against each other.

Front

What is fluid friction?

Back

Fluid friction is the resistance experienced by objects moving through a fluid (liquid or gas).

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from starting to move.

Front

How does surface roughness affect friction?

Back

Rougher surfaces generally create more friction, making it harder for objects to slide over them.

Front

What does friction produce when two surfaces rub together?

Back

Friction produces heat when two surfaces rub against each other.

Front

In which direction does friction act?

Back

Friction acts in the opposite direction of the movement of the object.

Front

What happens to friction when the weight of an object increases?

Back

As the weight of an object increases, the friction between the object and the surface also increases.
