Energies (Acosta)
Types of Energy
| Question | |
|---|---|
| What is known as the ability to do work or cause a change? | Energy |
| What is known as energy in motion and energy stored? | Mechanical Energy |
| What is known as energy in motion to an object? | Kinetic Energy |
| What is energy that is not causing any changes? | Potential Energy |
| What are the two types of potential energies that are known as stored energy and may cause changes later? | Gravitational Energy & Elastic Energy |
| What type of potential energy depends on the Earth’s gravity like a person falling or a car rolling down a hill? | Gravitational Energy |
| What type of potential energy is created from a bent or stretched object like a pole that will bend or a rubber band stretching out? | Elastic Energy |
| In sound energy, what is known as the back-and-forth motion of an object? | Vibrations |
| What kind of energy moves through the air as sound waves? | Sound Energy |
| How fast does sound energy travel in the air? | 330 meters per second |
| What is known as energy that is all around us and it can reflect, bend, or pass through objects? | Light |
| What are the three types of light capabilities on materials? | Transparent, Translucent, & Opaque |
| What does transparent mean in light? | It means light can pass through an object |
| What does translucent mean in light? | It means light can’t completely go through certain objects |
| What does opaque mean in light? | It means that light can’t pass through any of these objects. |
| In what direction does light move in? | In a straight line |
| What is known when light reflects or bounces off a object? | Reflection |
| What is known when light bends into new material in an angle different from 90 degrees? | Refraction |
| Light waves can have very long or very short wavelengths, what is it known as? | Electromagnetic Spectrum |
| What is the speed of light? | 186,000 Miles Per Second |
| Atoms are what to all matter in the universe? | Building Blocks |
| What are the three parts to an atom? | Protons, Electrons, & Neutrals |
| What parts of the atoms have the positive, negative, and neutral part of the atom? | Protons= + positive + part of an atom, Electrons= - negative- part of an atom, & Neutrals= no charge part of an atom. |
| What parts of an atom balances its structure? | The Positive (+) and Negative (-) charges balance the structure of an atom |
| When positive and negative charges of an object don’t balance, the object is charged and develops? | Static Electricity |
| Moving charges from an atom produced into electrical energy is found in 3 areas, what are they? | Sound, Light, and Heat Energy |
| Energy cannot be what into another form? | Made or destroyed, but changed or transformed |
| Electrical energy is used to make light bulbs work by changing into what? | Light Energy |
| What other form of energy is electrical energy changed into? | Energy of motion |
| Where do many electric devices get their power from? | Electrical Outlets |
| Electrical energy travels through power lines into what areas in towns or cities? | Homes, Schools, & Businesses |
| A material through which an electric charge can move easily is called what? | Conductor |
| What are some of the best conductors are made of? | Copper, Gold, Silver, and Aluminum |
| What are materials that prevent the flow of electric charge known as? | Resistor |
| What are strong resistors that can stop most electric currents to place or areas in towns or cities? | Insulators |
| Insulators are mainly made of materials, what are they? | Rubber, Plastic, Glass, or Dry cotton |
