Energy
Energy study guide
| Question | Answer |
|---|---|
| Name a type of energy that starts with M | Mechanical |
| Name a type of energy that starts with t | Thermal |
| Name a type of energy that starts with s | Sound |
| Name a type of energy that starts with e | electrical |
| Name a type of energy that starts with L | Light |
| Name the 3 types of heat transfer | Radiation, Convection, Conduction |
| What is energy | ability to cause change in matter |
| What is kinetic energy | the energy of motion |
| What is Potential energy | the energy something has because of its position or condition |
| What is Mechanical energy | the total potential energy and kinetic energy of an object. |
| What can light energy do | it is a form of energy that can travel through space. |
| What do plants use light energy for? | to make food |
| What is sound energy | energy from things moving back and forth (which creates sound waves of energy) |
| What is Chemical energy | energy that is released by a chemical change(think when we digest food for energy, that is a chemical change) |
| What is Electrical energy | energy that comes from an electrical current |
| Can energy change | It can change from one form to another |
| What is heat energy | heat is the energy that moves between objects of different temperatures |
| How does heat move naturally | Heat moves naturally from an object with a high temperature to one with a lower temperature. What is conduction |
| What is conduction transfere | it is the transfer, or movements, of heat between two objects that are touching. It can also occur within items (like warmth inside your body) |
| What is convenction transfer | is the transfer of heat with in a liquid or a gas (heat from a campfire warms the air around it) |
| What is a convection current | heat is conducted from a a burner to a pot of water, heated water moves to the top to war the cooler water. the cooler water sinks to the bottom,where it gets heated . It goes around in a circle or cycle |
| What is radiation transfer | radiation transfer is the transfer of yea without matter to carry it. |
| Insulators | Materials that do not conduct (allow it through) heat. Like an oven mitt |
| Why is it important to insulate your home? | Keeps the heat out in the summer, the heat in in the winter, saves on money paying energy bills and conserves energy. |
| What type of energy does an arrow have right before it is released from the arrow | Potential |
| What are examples of fossil fuels | gas, oil, coal |
| conductors | lets the heat easily transfer |
| What are example of conductors? | metal, water |
| What are example of insulators | thermos, insulation in your home |
| Which is the best aluminum, copper, steel or wood? | wood |
| Which material would keep something warm? foam, plastic, waxed paper or aluminum foil | Foam |
| how does a thermos work? | conduction and convection are stopped by glass in the vacuum, radiation is stopped by the reflective material |
| How is sound produced? | Vibrations |
| How does sound travel? | waves |
| What does sound not travel through | empty space |
| How does light travel? | waves |
| what does light travel through? | empty space |
| What are natural sources of light? | sun, fire |
| Thermal energy | heat energy, molecules moving faster make it |
| Mechanical energy | the energy of motion |
| Kinetic energy | moving objects |
| potential energy | objects at rest |
| Electrical | the movement of charged particles |
| What is heat? | the transfer of thermal energy from piece of matter to another. |
