Energy Flashcards
What is energy
Energy is the ability to do work.
What is kinetic energy
energy that a body has because it is moving - for example a ball rolling along the ground
What is potential energy
energy that a body has because of its position relative to other bodies - for example a stationary object raised above ground level; changing the shape of an object can also involve potential energy - for example when you bend a ruler
What is sound energy
energy that is produced by a vibration - for example the sound produced by a guitar string vibrating after it is plucked
What is heat energy
energy that travels between a hot object and a cool object - for example when a spoon is placed in hot tea, heat travels from the tea to your fingers along the spoon
What us chemical energy
energy that is stored in food is a good example of chemical energy
What is electrical energy
energy that comes from the flow of electric charge - for example, electric current flowing along a copper wire
What is solar energy
energy that comes from the Sun
What is nuclear energy
energy produced from nuclear reactions - for example nuclear fission or nuclear fusion.
