Force & Motion
This is defined as a push or pull
The ability to do work or make change happen
This is the basic unit of a chemical element
Atom
This is what is happening when you have burning, rotting, or bubbling and a NEW SUBSTANCE is formed
Chemical Change / Chemical Reaction
A wave is a disturbance that moves _________________ from place to place.
ENERGY
In Newton's First Law, it states that an object at rest tends to stay at rest and an object in motion tends to stay in motion. What is the word for this?
INERTIA
This is the word for energy of motion
Kinetic Energy
This is made up of at least two atoms
MOLECULE
physical change
This is the distance between two corresponding parts of a wave
Wavelength
This force pulls objects toward the center of the Earth.
Gravity
Which of the following is a type of kinetic energy? Elastic energy, Chemical energy, or Light energy?
LIGHT! The others are forms of potential energy.
How many atoms are there in the following molecule:
3H2O
9
This state of matter has particles with the least amount of motion.
SOLID
Which carries more energy: a wave with a big amplitude or a wave with a small amplitude?
BIG AMPLITUDE = Big Energy
What is the force between two objects in contact with one another that pushes in the opposite direction of movement?
FRICTION!
An ice cube melting in your hand is an example of what kind of thermal energy transfer?
CONDUCTION
This is where you can find a list of chemical elements, their atomic numbers, weights, and symbols.
The Periodic Table of Elements
This is change of state of matter from solid directly to gas (no liquid phase)
SUBLIMATION
In this kind of wave, the particles move up and down as the wave moves forward.
Transverse Wave
According to Newton’s Third Law, for every action there is this.
an equal and opposite reaction
This law states that energy cannot be created or destroyed, only transformed from one form to another.
Law of Conservation of Energy
This is a pure substance made of only one kind of atom.
In a chemical reaction, the substances you start with are called these, and the substances you end with are called these.
Reactants & Products
These types of waves do not need a medium to travel. They can go through space.
Electromagnetic waves
