200
An electrostatic attraction that forms between atoms when they share or transfer valence electrons.
What is a chemical bond?
200
A process that changes a substance into one or more different substances.
What is a chemical reaction?
200
The study of how things move.
What is kinematics?
200
The branch of physics that studies these forces and how they can change an object's motion.
What is dynamics?
200
The ability to do work.
What is energy?
400
A chemical bond formed as the result of two atoms sharing electrons.
What is a covalent bond?
400
*DOUBLE JEOPARDY*
A reaction that releases energy as heat.
What is a exothermic reaction?
400
A coordinate system that we can use to describe the motion of an object.
What is a frame of reference?
400
The tendency of matter to resist change in it's motion.
What is inertia?
400
The energy that objects possess due to their motion.
What is kinetic energy?
600
A shorthand way of identifying a chemical compound.
What is a chemical formula?
600
A reaction that absorbs more energy than it releases.
What is an endothermic reaction?
600
Any quantity that consist of magnitude, or size, only.
What is a scalar?
600
object at rest remain at rest, and objects in motion continue in a straight line at a constant velocity unless acted on by a net external force.
What is the law of inertia?
600
Stored energy that can be used later.
What is potential energy?
800
The attraction between metal atoms and their sea of shared electrons.
What is a metallic bond?
800
The energy needed to get a chemical reaction started.
What is activation energy?
800
*DAILY DOUBLE*
The distance traveled in an amount of time.
What is speed?
800
The acceleration of an object is directly proportional to the net force acting on the object and is inversely proportional to it's mass.
What is the law of acceleration?
800
The sum of any kinetic energy and all the forms of potential energy in a system.
What is mechanical energy?
1000
The name we use for unequal distribution of electric charge.
What is polarity?
1000
The speed of a reaction.
What is a reaction rate?
1000
A property of a moving system that is equal to it's velocity multiplied by mass.
What is momentum?
1000
For every action force, there is an equal and opposite reaction force.
What is the law of action-reaction?
1000
heat energy that originates deep within the earth's interior.
What is geothermal energy?
