Unit 2 Frayer Models The energy of an object that is due to the object s motion. Can be transferred from one moving object to another. Moving a soccer ball. A football passing through the field goal post. Kinetic An acorn hanging from a tree The energy of an object that is stored. Cannot be transferred When a rubber band is stretched and waiting to be released. A glass of milk Potential Blowing wind A person climbing a ladder Substances or objects that conduct thermal energy very well. is transferred rapidly. Iron skillet Cookie sheet Thermal Conductors Plastic spatula Flannel shirt
Substances or objects that do not conduct thermal energy very well. Thermal energy is transferred very slowly. A wooden tongue depressor. Oven mitt Thermal Insulators Curling iron Copper pipe The total energy of motion and position of an object. that an object has due to its position (potential energy) or due to its motion (kinetic energy). A moving car A book resting on a table A hammer hitting a nail Mechanical Thermal energy Sound energy Atoms Electron Produced by the vibrations of electrically charged particles. Ultraviolet light (unseen by human) Flashlight Light Causes energy to be transmitted, but does not need to be carried through matter (vacuum) Can be converted into other forms of energy Dog barking
Sound is the movement of energy through substances in longitudinal (compression/rarefaction) waves. Produced when a force causes an object or substance to vibrate; energy transferred through the substance in a wave. A vibrating drum Sound Lightbulb Total amount of energy cannot be created or destroyed, but can be changed from one form to another. is conserved in all cases. When a moving car hits a parked car and the parked car moves. Law of Conservation of Thoughts The transfer of thermal energy from one substance to another through direct contact. - One of the methods of thermal energy (heat) transfer. - Can occur within a substance. Placing a metal pole directly in a fire and the pole becomes hot. Conduction the Placing a metal pole outside in the sunlight.
The transfer of thermal energy by the movement of a liquid or a gas. Another method in which thermal energy is transferred. Boiling water in a pot (the water moves in roughly circular patterns. Convection Placing a metal pole directly in fire and the pole becomes hot. The transfer of thermal energy by electromagnetic waves, such as visible light and infrared waves. Sun (emits visible light, and infrared And ultraviolet waves) - A third way in which thermal energy is transferred. - Unlike conduction or convection, radiation can involve either an energy transfer between particles of matter or an energy transfer across empty space. Boiling water in a pot (the water moves in roughly circular patterns. Radiation The energy transferred between objects that are at different temperatures. Heat causes objects to feel hot or cold or to get hot or cold under the right conditions. A popsicle Fresh cup of hot cocoa Heat Absolute zero
The energy of moving electrons. Electrons are negatively charged particles of atoms. Electrical outlets Electrical Sun The ability to do work. Work is done when a force causes an object to move in the direction of that force. Light Heat Mass Time A change from one form of energy to another form of energy. Alarm clock (electrical energy to light and sound energies Transformati on Person sitting
When an object changes position over time relative to a reference point. Everything in the universe moves Hot air balloon Walking Motion Still standing
