The force of gravity on a person or object versus the amount of matter in an object.
What is the difference between weight and mass?
200
The total kinetic energy contained by a substance
What is thermal energy?
200
You use this to determine if an object is in motion
What is a reference point?
300
The outer electrons in an atom
What are valence electrons?
300
Observed as one increases in elevation
What is a decrease in air pressure?
300
Scientific principle that states that one object of greater mass will always attract an object of a smaller mass.
What is the Universal Law of Gravitation?
300
The transfer of thermal energy between objects that have differing temperatures
What is heat?
300
This occurs when an object changes speed and/or direction
What is acceleration?
400
The process of calculating atomic mass.
What is adding together the protons and neutrons?
400
Force that is exerted on a body immersed in a fluid, whether fully or partially submerged, that is equal to the weight of the fluid that the body displaces.
What is Buoyant Force?
400
The procedure used to produce a change in motion
What is an unbalanced force acting on an object?
400
A property that depends on the temperature, mass, and identity of the substance
What is thermal energy?
400
Describe an object's movement when it is represented by a flat horizontal line?
What is at rest or at a constant speed (no acceleration or deceleration)?
500
The most abundant element in the universe.
What is hydrogen?
500
Scientific law that states a change in pressure at any point in an enclosed fluid is transmitted equally through the fluid
What is Pascal's Law?
500
The relationship of the mass of two objects and the distance between them.
What are the two factors that affect the force of gravity?
500
The three forms of heat transfer
What is conduction (touching), convection (convection currents), and radiation (electromagnetic wave that can travel in space)?
