Name the four forms of matter
Solids, liquids, gases, and plasma
What is the definition of Energy?
Energy is the ability to do work or cause change
name the tool used to measure length and what unit of measure we use.
Ruler--centimeters, inches, etc.
Name the three forms of energy we know SO FAR
Thermal Energy, Potential Energy, Kinetic Energy.
What is the definition of potential energy?
Energy that is stored in a system.
What unit(s) of measure do we use to measure mass?
Kilograms, Grams.
What is Work?
Work is energy being transferred from one object to another. Typically a force.
Thermal energy excites the atoms that make up them change states.
Is this a chemical or physical change?
It's a physical change.
How do I turn my kinetic energy into potential energy
Using my kinetic energy to go up a hill, turning a generator, pushing a spring down with my hands, etc.
What are the 3 laws of conservation of energy
I CAN NOT create energy
I CAN NOT destroy energy
I can ONLY transform it
What measurement does a car use that is calculated using Speed = Distance/Time
MPH on a car
What is cold and how to I measure it?
Is "cold" something in science or is it a feeling?
Cold is a feeling people have about something that lacks thermal energy.
"Cold" is the lack of thermal energy in matter. There is no such thing as "cold" scientifically speaking.
You either have thermal energy or you don't.
Is light a form of energy or a form of matter?
Light is a form of energy, it is mass-less and by definition not made of matter.
Name two ways thermal energy is created.
Rubbing hands together, light being absorbed into an object.
What devices could I use to measure the amount of energy something has?
Thermometer (Thermal Energy), Speedometer (Kinetic Energy), RADAR (Kinetic Energy), Tension Gauge (Potential Energy)
