Physics
Newton's First Law states that _______
An object at rest will remain at rest, unless acted upon by an external force.
The difference between series and parallel circuits
A series circuit is a circuit where the current flows the same on only one path, whereas a parallel circuit has branches where the current flows the same on every component.
An atomic number is ____
The number of protons in an atom.
The two poles of a magnet.
North and South.
The function of the mitochondria.
Mitochondria produces/generates energy for the cell.
The equation for weight.
Weight = mass x gravity
The equation for Resistance. (Ohm's law)
Resistance = voltage/current
Heterogeneous vs Homogeneous mixtures.
Heterogeneous mixtures can be easily differentiated (e.g, cereal), while Homogeneous mixtures appear to be the same all throughout (e.g, air).
The relationship between Like poles vs Unlike poles.
Like poles repel each other, while unlike poles attract each other.
Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, and Nutrition.
To find displacement.
Measure the length of the starting point to destination in a straight line, then calculate the answer.
The unit for electric current.
I (amps).
True or False? All three atomic particles have mass.
False. Electrons do not have mass, while neutrons and protons have mass.
To draw a magnetic field that is strong, you have to draw the lines ____
Closer together. The stronger the magnetic field, the closer the lines get to each other.
The dichotomous key is used to ___
Identify animals based on their physical characteristics.
The maximum speed of an object attainable while falling.
Terminal speed.
___ terminal flows to the ____ terminal.
The positive terminal flows to the negative terminal.
The difference between ionic and covalent bonding between atoms.
Ionic bonding is where an atom takes electrons from or gives them to another atom. Covalent bonding is where two atoms are sharing electrons from each other. (e.g, O2)
Three components of an electromagnet.
Magnet, Cell/battery, and Wires.
The inventor of the Linnaean System in classifying animals.
Carolus Linnaeus.
What is Newton's Second Law? Bonus fifty points if you can provide the equation for it.
Force is equal to mass times acceleration.
Force = Mass x Acceleration
The equation for Voltage. Bonus fifty points if you can answer the equation for Current. (Ohm's law)
Voltage = Current x Resistance
Current = Voltage/Resistance
How many electrons are in the first and second shell? Bonus fifty points if you can name the amount of electrons in Oxygen.
First shell = 2
Second shell = 8
The amount of electrons in Oxygen is 8
What is faraday's law of induction?
"When a magnetic field changes, it causes a voltage, a difference in the electric potential that can make electric currents flow."
What are the four parts of blood? Bonus fifty points if you name the liquid part of blood.
