(Conservation and dissipation of energy) Exam Practice Flashcards
How can energy be transferred?
Energy can be stored in many different ways and transferred by heat, waves ,an electrical current or when a force moves an object.
What is a chemical energy store?
Energy stored in chemical bonds and transffered during chemical reactions.
Give examples of chemical energy stores
Food
Fuels
chemicals found in batteries
What is a Kinetic energy store?
Kinetic Energy Store: The energy of a moving object.
Examples of Kinetic Energy Stores
Runners
Buses
What is Gravitational Potential Energy?
The energy stored in a object at height.
Examples of Gravitational Potential Energy
Aeroplanes
Mugs on tables
Kites
What is Elastic Potential Energy?
The energy stored in a object when it is squashed or streched.
Examples of Elastic Potential Energy
Springs
Catapults
Inflated balloons
What is Thermal Energy Store?
The energy a substance has because of it’s temperature.
Hotter objects have more internal energy and they vibrate faster.
Example of Thermal Energy Store
Coffees
Human Bodies
What is a Nuclear Energy Store?
The energy stored in the nuclease of an atom.
Example of Nuclear Energy Store
Uranium Nuclear Power
Nuclear Reactors
What is electrostatic energy?
Electrostatic Energy:The energy stored when repelling charges have been moved closer or attracting charges have been moved further apart.
Examples of Electrostatic Energy
Thunder Clouds
