Potential Energy
batteries and food are an example of this form of energy
chemical energy
Jane's dog Sport jumped over a ball.
mechanical energy
These are the first 3 transformations that occurred when Ted struck a match and caught it fire, starting with the match.
chemical, mechanical, thermal
the sun warms the ground outside
radiation
What is the part of the experiment changed by the scientist?
Independent Variable
Don stepped on his pogo stick and the spring compressed
stored mechanical (elastic) energy
plugging your phone to charge it
electrical energy
The first 2 transformations that will occur in a car battery when it is turned on.
chemical to electrical
this works well in solids
conduction
This is data or what is measured by the scientist.
Dependent Variable.
a lot of energy is released from the splitting of uranium atoms
nuclear energy
a fire warming your hands
thermal energy
The 3 transformations that occur in a flashlight
chemical, electrical, and light
noodles get cooked in boiling water
convection
This is not changed and used to compare to the tested variable.
Control group
A mirror that hangs on the wall is an example of this.
gravitational (potential) energy
cooking food in a microwave
Electromagnetic (light) energy
The 3 transformations that occur when Julie chopped wood with an ax.
chemical, mechanical, and sound
You burn your feet on the hot sand.
conduction
This is an educated guess to a possible outcome in an experiment.
Hypothesis
Give 2 types of potential energy.
chemical, stored mechanical, nuclear, and gravitational
This can travel through empty space.
Electromagnetic (light) energy
The four energy transformations that occur in an electric pencil sharpener
electrical, mechanical, sound, thermal
energy always moves this way
warmer to cooler
What is the unit for measuring mass?
