What is potential energy?
Potential energy is stored energy.
What is kinetic energy?
Kinetic energy is energy that is in motion.
What is electromagnetic energy?
Electromagnetic energy is electrical and magnetic waves that can travel through a vacuum or space.
What energy can travel through a vacuum?
Electromagnetic energy can travel through a vacuum. Specifically electric and magnetic waves.
What is energy?
Energy is the ability to do work or make something happen.
What is the electromagnetic spectrum?
The electromagnetic spectrum shows the relationship between wavelength and frequency.
What is heat energy/thermal energy?
Heat energy is the energy of moving particles, which is also kinetic energy.
What is conduction?
Conduction is when heat energy travels through solids.
What is convection?
Convection is the transfer of heat through gases and liquids.
What is radiation?
Radiation is the transfer of heat energy through space or gas.
What is a convection current?
A convection current is the circular movement of heat when hot air or liquid rises and colder air or liquid sinks.
What is a conductor?
A conductor is the transfer of heat and electricity.
What is an insulator?
An insulator is something that does not transfer heat and electricity.
What is mechanical energy?
Mechanical energy is the energy of moving parts of machines or human parts.
What is sound energy?
Sound energy is energy produced by vibrating sound waves.
What is Newton’s 1st Law?
Newton’s first law states that an object in motion will stay in motion unless it is acted upon by an unbalanced force.
What is Newton’s 2nd Law?
Newton’s 2nd Law is force=mass•acceleration
What is Newton’s 3rd Law?
Newton’s 3rd Law is that for every action, there is an equal but opposite reaction.
What is vaporization?
Vaporization is when a liquid changes to a gas, (evaporation) or a solid changes to a gas. (Sublimation)
What is a compound?
A compound is a substance made up of 2 or more elements that are chemically combined.
What is a mixture?
A mixture is 2 or more substances that are physically combined.
What is a solution?
A solution is a mixture of 2 or more substances.
What is a solvent?
A solvent is most of the solution.
What is a solute?
A solute is the substance that dissolves.
