The sum of an object's kinetic energy and potential energy
What is Mechanical Energy
100
All of the particles that make up matter are constantly in motion. Because they are in motion, they have kinetic energy.
What is the kinetic theory of matter
100
The total kinetic energy of all particles in a substance.
What is Thermal Energy
100
The energy transferred from an object at a higher temperature to an object at a lower temperature.
What is Heat
100
The ratio of useful output energy to input energy.
What is Efficiency
200
This energy results from the vibration of particles
What is Sound Energy
200
A measure of the average kinetic energy of all the particles in an object.
What is Temperature
200
This is what thermal energy is measured in.
What is joules
200
What 2 ways are heat measured in
What is the Calorie and Joules
200
Energy cannot be created or destroyed. It can only change forms
What is the law of conservation of energy
300
Transmitted through space in the form of electromagnetic waves
What is Electromagnetic Energy
300
Equally spaced units between two points.
What are Degrees
300
Temperature is related to the AVERAGE kinetic energy of particles, while thermal energy is the TOTAL kinetic energy of all the particles.
What is the difference between temperature and thermal energy
300
The amount of energy needed to raise the temperature of 1 gallon of water by 1 degree Celcius
What is one calorie
300
A temperature scale used commonly by physicists
What is the Kelvin scale
400
The energy an object has due to the motion of its molecules. The faster the molecules in an object move, the more of this type of energy the object has.
What is Thermal Energy
400
Temperature is measured using an instrument called this
What is a Thermometer
400
Between a glass of water and a lake, which would have more thermal energy, assuming both have the same temperature.
What is a lake (because a lake has many more water molecules)
400
The transfer of energy as heat from one substance to another through direct contact.
What is Conduction
400
The transfer of energy as heat by the movement of liquid or gas.
What is Convection
500
The temperature scale most commonly used around the world, and the temperature scale used most commonly in the US
What is Celsius and Fahrenheit
500
When two objects at different temperatures come into contact, energy is always transferred this way
What is from the object that has the higher temperature to the object that has the lower temperature
500
A material that transfer heat very well, and a material that is a poor conductor of heat.
