Force and Friction

Front

What is air resistance?

Back

A type of friction that occurs when air pushes against a moving object, causing it to negatively accelerate.

Front

What are the two components of a force?

Back

Strength and direction.

Front

What is the unit of measurement for force?

Back

Newton.

Front

What type of friction occurs when an object is not moving?

Back

Static friction.

Front

What does it mean if an object has a net force greater than 0 Newtons?

Back

The object is unbalanced and accelerating.

Front

What is friction?

Back

A force that opposes the motion of an object.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are sliding past each other.

Front

What factors affect the amount of friction between two surfaces?

Back

The types of surfaces in contact and the force pressing them together.

Front

What is sliding friction?

Back

The friction that occurs when two surfaces slide against each other.

Front

What is rolling friction?

Back

The friction that occurs when an object rolls over a surface.
