Forces, Friction, and Newton's Flashcard Review

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

The four types of friction are: 1. Static Friction, 2. Sliding Friction, 3. Rolling Friction, 4. 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 friction?

Back

Sliding friction is the force that opposes the motion of an object as it slides over a surface.

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

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What is a force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.
