Vocabulary
The ability to do work or cause change is called this.
What is energy?
Energy that is stored is called this.
What is potential energy?
This is the energy needed to move a 1 Newton apple a distance of 2 meters.
What is 2 Joules?
This is the average kinetic energy of matter in an object.
What is temperature?
This is an example of kinetic energy.
Anything in motion (rollercoaster moving downhill, stream flowing, waving arms, etc.)
This is the energy found in the chemical bonds between atoms.
What is chemical energy?
This type of energy is formed by the movement of photons.
What is light energy?
A diver on top of a diving board that is 6 meters above the ground will have this amount of potential energy if they weigh 20 Newtons.
What is 120 Joules?
The giant ice sculpture would have more of this than a lit match.
What is thermal energy?
This is the type of heat transfer that allows our planet to be heated by the Sun.
What is radiation?
This is the total amount of heat energy in a given mass.
What is thermal energy?
This type of heat transfer involved the cycling of matter in a liquid or gas, with hot thing rising and cold things falling.
What is convection?
These are the two main factors that affect the kinetic energy of a moving object.
What are mass and velocity?
These are the two SI units for measuring temperature.
What are degrees Celsius and Kelvin.
These are the two factors that affect the potential energy of an object.
What are weight and height.
Name the two main types of energy.
What are potential and kinetic energy?
A swinging pendulum can show how this type of energy is converted into this other type of energy.
What are potential and kinetic energy?
A pendulum with a mass of 5 kg is moving at a velocity of 5 m/s. This is the kinetic energy of the pendulum.
What is 62.5 Joules.
This is the fastest method of heat transfer.
What is conduction?
According to this law, energy cannot be created or destroyed.
What is the law of conservation of energy?
This is the mathematical formula for calculating kinetic energy.
What is 1/2 x mass x velocity squared?
The ability to move a 1 Newton force a distance of 1 meter is known as this.
What is a Joule?
The amount of kinetic energy for an object is measured before and after a chemical reaction. If the kinetic energy was found to quadruple after the reaction and the mass of the object stayed the same, then this must have happened to the velocity of the object.
The velocity of the object doubled.
The movement of clouds and weather systems in our atmosphere is made possible due to this method of heat transfer.
What is convection?
Digesting food is an example of transferring this type of energy to another type of energy.
What is chemical energy to mechanical energy?
