Energy
Work and Speed
100
A process used to solve a problem.
What is an experiment?
100
at the top
What is potential energy the greatest?
100
force and a distance
What are the 2 variables needed in order to say "work" was done?
200
one!
How many variables should you change at one time?
200
At the bottom but still moving.
What is kinetic energy the greatest?
300
The one variable that "I" change in the experiment.
What is an independent variable?
300
39.2 J
What is potential energy if there is a mass of 2 kg, and a height of 2 m. Potential Energy= mass x gravity x height
400
quantitative: 2 apples qualitative: red apples
Give an example of each: quantitative and qualitative data.
400
50 J
If there is 50 J of kinetic energy at the bottom of the track, how much potential energy is there at the top? (if there is no friction!)
500
quantitative
What type of data is more accurate in an experiment?
500
Law of Conservation of Energy
What is the law that states that energy is not created nor destroyed?
