Potential and Kinetic Energy
The ability to do work (cause change).
What is energy?
Energy carried by sound waves.
What is sound energy?
When one form of energy is converted to another form of energy, this occurs.
What is energy transformation?
The movement of thermal energy from a high temperature to a lower temperature.
These electromagnetic waves are detected by the human eye.
What are visible light waves?
Energy that is stored due to the interaction of objects or particles.
What is potential energy?
A disturbance that transfers energy from one place to another without transferring matter.
What is a wave?
What is the law of conservation of energy?
The measure of average kinetic energy of the particles in a material.
What is temperature?
These electromagnetic waves can damage human skin, so humans wear sunscreen for protection.
What are ultraviolet rays?
Energy of motion.
What is kinetic energy?
The energy carried by electromagnetic waves.
What is radiant energy?
An energy resource that is used faster than it can be replaced by nature.
What is a nonrenewable energy resource?
The transfer of thermal energy through collisions between particles in matter.
What is conduction?
These electromagnetic waves vibrate water molecules, causing materials that contain water to heat up.
What are microwaves?
Energy stored in and released from the nucleus of an atom.
What is nuclear energy?
The sum of the kinetic and potential energy of the particles that make up an object.
What is thermal energy?
An energy resource that is replace as fast or faster than it is used.
What is a renewable resource?
The transfer of thermal energy by electromagnetic waves.
What is radiation?
These two electromagnetic waves are ionizing, and can cause serious injuries to humans.
What are x-rays and gamma rays?
Energy stored in and released from the bonds between atoms.
What is chemical energy?
The sum of the kinetic and potential energy in a system.
What is mechanical energy?
A system that exchanged matter or energy with the environment.
What is an open system?
A material in which thermal energy moved slowly.
What is a thermal insulator?
Describe the 4 energy transformations that occur from a radio station studio to the radio in a car.
Sound converted to electrical energy.
Electrical energy is converted to light through radio waves.
Light converted back to electrical energy.
Electrical energy is converted back to sound.
