What is the smallest unit of an element called?
atom
molecule
cell
proton
What do we call a material that electricity can pass through easily?
conductor
insulator
plastic
rubber
What happens when two magnets are brought close together with the same poles facing each other?
They repel each other.
They attract each other.
They stick together.
Nothing happens.
What is the term for the highest point of a wave?
What is the crest?
What is the trough?
What is the amplitude?
What is the wavelength?
How is a wave frequency defined?
It is the number of waves that pass a point in 1 second.
It is the distance between two crests of a wave.
It is the height of the wave from its rest position.
It is the speed at which the wave travels.
What is the pH scale used to measure?
the acidity or basicity of a solution
the temperature of a solution
the density of a solution
the color of a solution
What is the relationship between wavelength and frequency in waves? What is its equation?
As wavelength increases, frequency decreases, and vice versa, which can be expressed as v = f x λ
As wavelength increases, frequency also increases, which can be expressed as v = f + λ
Wavelength and frequency are unrelated, and the equation is v = f / λ
As frequency increases, wavelength remains constant, which can be expressed as v = λ - f
What is the law that states matter cannot be created or destroyed in a chemical reaction?
Law of Conservation of Mass
Law of Definite Proportions
Law of Multiple Proportions
Law of Constant Composition
What is the unit of measurement for electrical resistance?
ohm
watt
volt
ampere
Ohm’s Law is expressed mathematically as:
V = I/R
V = IR
I = VR
R = VI
What are Newton’s 3 Laws of Motion?
1. An object at rest stays at rest and an object in motion stays in motion unless acted upon by an external force. 2. The force on an object is equal to its mass times its acceleration (F=ma). 3. For every action, there is an equal and opposite reaction.
1. Energy cannot be created or destroyed. 2. The total energy of an isolated system remains constant. 3. Energy can only be transferred or changed from one form to another.
1. The speed of light is constant in a vacuum. 2. Time slows down as you approach the speed of light. 3. Mass increases with velocity.
1. Every object attracts every other object with a force. 2. The force is proportional to the product of their masses. 3. The force is inversely proportional to the square of the distance between them.
What do we call a substance made of two or more different elements chemically bonded together?
compound
mixture
element
solution

What is the process called when a solid turns into a gas without passing through the liquid state?
sublimation
condensation
melting
freezing
What happens when you cut a magnet in half?
Each half becomes a new magnet with its own north and south pole.
One half becomes a north pole and the other becomes a south pole.
The magnet loses all its magnetic properties.
Only one half remains magnetic while the other becomes non-magnetic.
What do we call the area around a magnet where its force can be felt?
magnetic field
electric circuit
gravitational pull
thermal zone
What is a device used to open or close a circuit called?
switch
resistor
battery
bulb
What is the name of a magnet that is made by electricity?
electromagnet
permanent magnet
bar magnet
horseshoe magnet
