What is an atom?
A subatomic particle
The smallest unit of ordinary matter
An element
An electron
What is a molecule?
A really big atom
A subatomic particle
A collection of any two or more atoms
A single hydrogen atom
What is an element?
A group of the same atoms (have the same number of protons)
A group of atoms that have different qualities than the other atoms
Water
I don't know
Which of the following examples are incorrect?
These are all correct
What is the difference between a molecule and an element?
Elements have only protons
Elements can only be made of one type of atom, and molecules can have a variety of atoms
Molecules cannot contain any neutrons, and Elements need to contain at least 7 neutrons
Elements are made of different types of atoms
How do waves transfer energy?
Through the vibration of the particles
Through heat
Through the vacuum of space
Through opaque objects
How do sound, light, and water waves differ?
Sound waves travel through water and make noise, water waves move on top of clouds, and light waves move in curvy lines through space
Sound waves travel through air and make colors, water waves move below water, and light waves move in straight lines through the ocean
Sound waves travel through air and make noise, water waves move on top of water, and light waves move in straight lines through space
They are all the same
What is amplitude?
The vertex of a wave
The length from one point on a wave to an identical point on the next wave
The length from the top of the wave to the bottom of a wave
The length from halfway in between the wave, to the top of the wave
What is a wavelength?
The vertex of a wave
The length from one point on a wave to an identical point on the next wave
The length from the top of the wave to the bottom of a wave
The length from halfway in between the wave, to the top of the wave
What is frequency?
The number of vertexes a wave has, divided by 3
The amount of energy a wave carries
The amount of light beams that are intersecting each other
The number of waves to occur in a fixed unit of measurement
How are water, sound, and light waves alike?
They all transfer energy
They are all mechanical waves
They travel without a medium
There are no traits that all 3 waves share
How does light travel?
As a vacuum through space
As a wave
In an atom
Through planets
What is reflection?
The return of light or sound waves from a surface
The change in direction of a wave passing from one medium to another caused by its change in speed.
Appears to be the color of the filter
Allows most light to pass through, appears blurry
What is refraction?
The return of light or sound waves from a surface
The change in direction of a wave passing from one medium to another caused by its change in speed.
Appears to be the color of the filter
Allows most light to pass through, appears blurry
What is transparent?
The return of light or sound waves from a surface
The change in direction of a wave passing from one medium to another caused by its change in speed.
Allows all light to pass through, see clearly
Allows most light to pass through, appears blurry
What is translucent?
The return of light or sound waves from a surface
The change in direction of a wave passing from one medium to another caused by its change in speed.
Allows all light to pass through, see clearly
Allows most light to pass through, appears blurry
What is opaque?
The return of light or sound waves from a surface
The change in direction of a wave passing from one medium to another caused by its change in speed.
Allows all light to pass through, see clearly
No light passes through, light is absorbed
What is a usually reversible change in the physical properties of a substance, such as size or shape?
Chemical change
Physical Change
What is a usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties?
Physical change
Chemical change
Physical change is within the atoms and chemical is the appearance
True
False
Which is true?
Chemical change creates something new
Physical creates something new
Physical change alters the chemical properties
Chemical change’s matter stays the same
What is the difference between physical and chemical changes?
a chemical change produces a new substance, while a physical change does not.
a physical change produces a new substance while a chemical change does not
A physical change can’t be reversed
What is potential energy?
Stored energy or energy ready to be released
Energy in motion
Stored energy or energy ready to be added
Waves in motion
What is kinetic energy?
Stored energy or energy ready to be released
Energy in motion
Stored energy or energy ready to be added
Waves in motion
Look at the drawing of the ball bouncing. Which of the following is the correct sequence of words to use to indicate the different types of energy shown in the drawing?
Kinetic, potential, potential, kinetic
Potential, kinetic, potential, kinetic
Potential, potential, kinetic, kinetic
Potential, kinetic, kinetic, potential
The smaller the amount of mass, the more potential energy an object has
True
False
How does potential energy decrease?
When an object has stored energy
When an object falls
As the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy
True
False
How can an object be moved by another object?
Force can make things move, change shape or change their speed.
They bump into each other
Their atoms move
What is Newtons first law?
The force on an object is equal to its mass times its acceleration
When two objects interact, they apply forces to each other of equal magnitude and opposite direction.
An object will not change its motion unless a force acts on it
What is Newton's second law of motion?
the force on an object is equal to its mass times its acceleration
when two objects interact, they apply forces to each other of equal magnitude and opposite direction
an object will not change its motion unless a force acts on it
What is Newton’s third law of motion?
The force on an object is equal to its mass times its acceleration
When two objects interact, they apply forces to each other of equal magnitude and opposite direction.
An object will not change its motion unless a force acts on it
What is the difference between force and motion?
Force is what causes motion
Motion causes force
They are the same
