The force that resists the motion of two surfaces that are touching.
What is friction?
Stored Energy.
What is potential energy?
The transfer of energy that occurs when force is applied over a distance.
What is work?
The ratio of weight of all the air above you to your surface area.
What is atmospheric pressure?
An object in motion stays in motion and an object at rest, stays at rest unless acted upon by an outside force.
What is Newton's First Law of Motion?
Energy in Motion.
What is kinetic energy?

What is a simple machine?
A substance that can flow and take the shape of it's container.
What is a fluid?
For every action there is an equal and opposite reaction.
What is Newton's Third Law of Motion.
An energy resource that is available in limited amounts or that is used faster than it is replaced in nature.
What is a nonrenewable energy?
An axle attached to the center of a wheel and both rotate together.
What is wheel and axle?
An upward force applied by a fluid.
What is buoyant force?
The tendency of an object to resist a change in motion.
What is inertia?
Energy can be transferred from one form into another, but never created or destroyed.
What is the Law of Conservation of Energy?
A flat, sloped surface.
What is an inclined plane.
A force that opposes the motion of an object through a fluid.
What is drag force?
Forced that cause an object to move.
