|---|---|---|---|---|---|
| Energy | The ability to cause changes in matter; involves either motion or position; can be in many different forms
🗑
|
||||
| Heat Energy | The energy of moving particles of matter (example: electrical and chemical energy can be used to produce heat)
🗑
|
||||
| Solar Energy | Energy from the Sun that provides light and heat for Earth; solar energy can be used to generate electricity
🗑
|
||||
| Chemical Energy | The energy stored in chemicals, fossil fuels, and substances that can burn
🗑
|
||||
| Electrical Energy | The energy flowing in an electric circuit (source: batteries, generators)
🗑
|
||||
| Mechanical Energy | The energy of moving objects (example: any moving object, falling water, moving machine parts)
🗑
|
||||
| Kinetic Energy | The energy something has because it is moving
🗑
|
||||
| Potential Energy | The energy something stores because of position or structure
🗑
|
||||
| Law of Conservation of Energy | The amount of energy you start with is the amount of energy you end with; the amount of energy always stays the same though its form may change
🗑
|
||||
| Magnetism | The force of attraction or repulsion of magnetic materials
🗑
|
||||
| Magnetic Field | The area surrounding a magnet that applies magnetic force
🗑
|
||||
| Electromagnet | A coil of wire that uses an electric current to make strong magnetic force
🗑
|
||||
| Generator | A machine that changes one form of energy to another, especially mechanical energy into electrical energy; produces an electric current when a coil of wire wrapped around an iron core is rotated near a magnet
🗑
|
||||
| Motor | A device that changes electrical energy into mechangical energy; contains an electromagnet
🗑
|
||||
| Electrical Circuit | The path through which electricity flows; electricity on a circuit can change to light, sound, heat, or motion by devices/loads added to the circuit
🗑
|
||||
| Conduction | The transfer of heat between objects that are touching, or from one part of an object to another
🗑
|
||||
| Convection | The transfer of heat that happens when the particles of a gas or liquid flow within the material itself
🗑
|
||||
| Radiation | The transfer of energy through space without any particles of matter touching or moving
🗑
|
||||
| Work | Occurs on an object when a force causes the object to move a distance; the object must move in response to the force
🗑
|
||||
| Machines | A device that makes work easier by reducing the amount of effort force or changing the direction in which the force is exerted
🗑
|
||||
| Effort Force | The force applied over a distance
🗑
|
||||
| Simple Machines | Any tool that is made up of only one or two parts
🗑
|
||||
| Lever | A simple machines made up of a rigid bar or board that is free to move around a fixed point called a fulcrum
🗑
|
||||
| Load | The weight or object that is moved using a simple machine
🗑
|
||||
| Fulcrum | The point at which a lever is supported
🗑
|
||||
| Effort Arm / Distance | The distance on a lever from the point at which the effort force is applied to the fulcrum
🗑
|
||||
| Pulley | A simple machine consisting of a rope that passes over a grooved wheel
🗑
|
||||
| Inclined Plane | A simple machine consisting of a slanted, flat surface
🗑
|
||||
| Complex Machine | A device that uses two or more simple machines, also known as a compound machine
🗑
