Energy (Form 1). Flashcards
Define kinetic energy.
Kinetic energy is the energy that an object has when it is moving.
Define potential energy.
Potential energy is stored energy that can be released to do work.
They are different types of potential energy: Name them.
They are different types of potential energy: gravitational potential energy, elastic potential energy, and chemical potential energy.
Describe gravitational potential energy.
Gravitational potential energy is the energy stored in an object as the result of its vertical position or height.
Describe elastic potential energy.
Elastic potential energy is energy stored as a result of applying a force to deform an elastic object.
Describe chemical potential energy.
Chemical potential energy is the energy stored in the chemical bonds of a substance.
Describe light energy.
Light energy is a kind of kinetic energy capable of allowing various forms of lights visible to the human eyes.
Describe heat energy.
Heat energy is defined as the flow of energy from a warm object to a cooler object.
Define energy.
Energy is the ability to do work.
Describe sound energy.
Sound energy is energy that is produced when an object or substance vibrates.
There are two main groups of energy sources: Name them.
There are two main groups of energy sources: Renewable energy sources and non-renewable energy sources.
Define renewable energy source.
A renewable energy source means energy that is sustainable - something that can’t run out, or is endless.
Define non-renewable energy source.
Non-renewable energy comes from sources that will run out or will not be replenished in our lifetimes.
Name 4 renewable energy sources.
Renewable energy sources include hydropower, wind power, solar power, and biofuels.
Name 2 sources of non-renewable energy source.
Non-renewable energy source include fossil fuels and nuclear power.
