300
What are the three ways heat is transferred?
Conduction, convection, radiation
300
What is convection heat transfer?
The transfer of heat through gasses liquids.
300
Explain exponential growth.
Exponential growth is when a pattern of data shows a greater increase with the passing of time.
400
It is the stored energy or energy due to the position is known as what kind of energy.
potential energy
400
What is gravitational potential energy?
Energy an object possesses because of its position in a gravitational field.
400
What is temperature a measurement of?
The average kinetic energy of the atoms in a substance.
400
What is conduction heat transfer?
Heat transfer through objects that are directly touching.
400
Give an example of energy conversion.
Any example where we start with one type of energy and it converts to a different type of energy. My example is the light switch (electrical energy) being turned on to turn on the lights (light energy).
500
What is the relationship between potential and kinetic energy?
As potential energy is decreasing, kinetic energy is increasing.
500
What is elastic potential energy?
Energy stored as a result of applying a force to deform an elastic object. The energy is stored until the force is removed and the object.
