Forces and Friction Flashcard

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 types of friction?

Back

The main types of friction are static friction, sliding (kinetic) friction, rolling friction, and fluid friction.

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

What is sliding (kinetic) friction?

Back

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

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of a rolling object, such as a wheel or ball.

Front

What is fluid friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas).

Front

How can friction be reduced?

Back

Friction can be reduced by making surfaces smoother, using lubricants, or changing the type of friction (e.g., from sliding to rolling).

Front

What is the net force?

Back

The net force is the overall force acting on an object, taking into account all individual forces and their directions.

Front

What happens to an object when the net force is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant velocity.

Front

What is the effect of rough surfaces on friction?

Back

Rough surfaces have greater friction compared to smooth surfaces.
