What is FALSE?
Work increases when ____ or ____ increases.
What are force and displacement?
The energy in objects or particles when in motion.
What is kinetic energy?
The unit of force in physics
What is a Newton?
This type of energy is inversely proportional to kinetic energy.
What is potential energy?
Decreasing this variable can decrease power.
What is work, force, OR displacement?
When work occurs in the vertical direction, it can change this.

What is friction (or another non-conservative force)?
The energy source originating deep within the earth.
What is geothermal energy?
The unit for power in physics
What is a Watt?
Total energy is represented by this mathematical expression.
What is kinetic plus potential energy? (What is total mechanical energy?)
The qualitative (in words) definition for the Law of Conservation of Energy.
What is "Energy cannot be created or destroyed, rather changed from one type of energy to another or from one object to another?"
This causes energy to be lost in a system.
What is a non-conservative force, such as friction or air resistance?
Fossil fuels are ________ energy but problematic because they have a ______ supply.
What is "cheep and abundant" and "finite?"
Freddy is enjoying his 100 g ice cream cone while sitting at the top of a Ferris Wheel, 100 m up from the ground, when the ice cream falls off his cone towards the ground below. What is the velocity as it hits the ground?
What is about 45 m/s?
