Introduction + Forms of Energy I
The ability to do work
What is energy?
Potential and kinetic energy
What are the two main types of energy?
Heat transfer caused when two objects come into direct contact. Most effective in solids.
What is conduction?
A type of energy caused by the movement of particles inside substances
What is heat?
Something that we need for every experiment to protect ourselves
What are safety glasses?
The units that we measure energy in
What are joules?
Stored energy
What is potential energy?
Heat transfer in liquids and gases
What is convection?
The measurement of how much the particles in a substance are moving
What is temperature?
A piece of equipment used to heat substances in experiments
What is a Bunsen burner?
Energy stored in an object when there is temporary strain on it
What is elastic energy?
Movement energy
What is kinetic energy?
Heat transfer that does not require a medium
What is radiation?
Conduction, convection and radiation
What are the three types of heat transfer?
Equipment used to measure time during an experiment
What is a stopwatch?
Energy stored in the bonds of chemical compounds
What is chemical energy?
Energy related to the movement of electric charges
What is electrical energy?
A material that is very good a conducting heat
What is a metal?
The Sun, a fire, a light bulb etc
What are some sources of heat?
Something we use to prevent burning our hands on hot equipment
What are tongs?
Energy that we can hear
What is sound energy?
What is gravitational energy?
Movement of particles in a liquid or gas that form when a substance is heated unevenly
What is a convection current?
Heat is a type of energy, temperature is a measurement
What is the difference between heat and temperature?
Equipment used to hold other equipment up during an experiment
What is a tripod?
