|
Energy |
The ability to do work. |
|
|
Potential Energy |
Energy that is not in motion but could be. |
|
|
Kinetic Energy |
Energy that is in motion. |
|
|
Force |
A push or pull that gives energy. |
|
|
Friction |
A force that opposes, or goes against, motion. |
|
|
Inertia |
The property of matter to resist change. |
|
|
Pressure |
A force acting on a surface area. |
|
|
Buoyancy |
The ability to float in air, water, or some other fluid. |
|
|
Weight |
Is a force that is caused by gravity and mass. |
|
|
Boyle's Law |
Having to do with the volume and pressure of a gas. With a greater volume there will be less pressure, and with a smaller volume there will be more pressure. |
|
|
Charles' Law |
Explains the pressure of a gas under certain temperatures. As the temperature increases so does the pressure, and as the temperature decreases so does the pressure. |
|
|
Momentum |
The product of Mass times Velocity. P = MV |
|
|
Speed |
The distance an object travels per unit of time. D/T = Speed |
|
|
Acceleration |
The rate of increase in speed. |
|
|
Work |
The product of a force applied to an object and the distance moved. |
|
|
Power |
The rate at which work is done. W/T = Power |
|
|
Machine |
A devise that makes work easier by changing the size or direction of a force. |
|
|
Mechanical Advantage |
The amount by which the applied force is multiplied by a machine. |
|
|
Wedge |
An incline plane that moves. |
|
|
Screw |
An incline plane wrapped around a cylinder to form a spiral. |
|
|
Fulcrum |
The pivot point of a lever. |
|
|
Pulley |
A belt or rope wrapped around a wheel. |
|
|
Block and Tackle |
Two or more pulley's that decrease the force needed. |
|
|
Compound Machine |
A machine that is made up of two or more simple machines working together. |
|
|
Newton's 1st Law |
An object at rest will remain at rest until acted on by an outside force. |
|
|
Newton's 2nd Law |
When a force acts on an object, the bigger the force the bigger the change on the object. |
|
|
Newton's 3rd Law |
For every action there is an equal and opposite reaction. |
