What is Energy conversion
This theory states that all matter is made up of molecules that are always moving
What is the Kinetic Molecular Theory
This type of heat transfer occurs when thermal energy moves through direct contact between objects or particles
What is Conduction
Objects fall at the same speed no matter the mass is an example of...
What is the Universal Law of Gravitation
What is the definition of power?
What is the rate at which work is being done
What law states that energy is never created or destroyed?
What is the Law of Conservation of Energy
What are molecules doing in each phase of matter?
Solids: stable & fixed shape
Liquids: flows & fixed volume
Gases: expands freely
Is the amount of heat used in the phase change from liquid -> gas

B) Latent Heat of Vaporization
B) Latent Heat of Vaporization
What force pulls an object out of its straight-line path into a circular path?
What is Centripetal Force
What is the equation for work?
Work=Force x distance
Working against inertia, gravity, friction, or shape are all examples of...
What is Resisting Force
Attraction of two DIFFERENT molecules is...
What is Adhesion
Name the three Phase Changes
What is:
Melting solid -> liquid
Evaporation liquid -> gas
Sublimination gas -> solid
What is the mathematical formula that Newton uses for gravitational force? Hint: Equation
What is F=G(m1m2/d2)
If a car gets stuck in the snow is pushed and does not move did work occur?
No
Force was applied but no distance was covered.
List the five energy forms
What is mechanical, chemical, radiant, electrical, and nuclear energy
Two of the SAME molecules interact as solids or liquids is...
What is Cohesion
This type of heat transfer happens in fluids when warm material rises and cooler material sinks, creating a circulating current.
What is Convection
