periodic motion and waves
200
An electrostatic attraction that forms between atoms when they share or transfer valence electrons.
What is a chemical bond?
200
A chemical reaction that releases more thermal energy than it absorbs.
What is an exothermic reaction?
200
The study of how things move.
What is kinematics?
200
The branch of physics that studies forces and how they can changes an object's motion.
What is dynamics?
200
Motion that repeats in equal time intervals.
What is periodic motion?
400
A positive or negative number showing the electric charge on an element when it forms a compound.
What is the oxidation state?
400
A chemical reaction that absorbs more thermal energy than it releases.
What is an endothermic reaction?
400
How far an object moves during a time interval.
What is distance?
400
A force that only acts when one object touches another.
What is contact force?
400
A change in wave direction due to a change in a waves speed as it enters a new medium.
what does refract mean?
600
The principle that states that atoms generally are most stable when they have eight electrons in their valence energy level.
What is the octet rule?
600
The minimum energy needed for a chemical reaction to occur.
What is activation energy?
600
A vector quantity that describes a change in position.
What is displacement?
600
🥳DAILY DOUBLE🥳
The law that states that objects at rest remain at rest and objects in motion continue in a straight line at a consistent velocity unless acted on by a net external force; also called Newton's first law of motion.
What is the law of inertia?
600
A region of lower density and pressure in a longitudinal wave.
what does rarefaction mean?
800
A system for modeling the covalent bonds between atoms in a molecule and any unbonded electrons in the molecule.
What is the Lewis structure?
800
The law that states that energy cannot be created or destroyed but only transferred between objects or transformed; also known as the first law of thermodynamics.
What is the law of conservation of energy?
800
The rate of change in velocity.
What is acceleration?
800
A pulling force that is transmitted through a rope, chain, or similar object.
What is tension?
800
A disruption that carries energy from one location to another.
What is a wave?
1000
A group of covalently bonded atoms that together have gained or lost electrons and act as a single ionized particle.
What is a polyatomic ion?
1000
🥳DAILY DOUBLE🥳
The principle that states that a chemical system in equilibrium will adjust its equilibrium position in such a way as to reduce the effect of any changes made to a system.

What is Le Châtelier's principle?
1000
Acceleration that causes an object to move along a circular path.
What is centripetal acceleration?
1000
A force that accelerates an object toward the center of a circular path.
What is centripetal force?
1000
The bending of waves off a around an obstacle or through an opening.
What does diffract mean?
