What is the largest planet in our solar system?
Jupiter
A ball sitting on a shelf has what type of energy?
Potential energy (gravitational potential energy)
This is the tiny, dense center of an atom that contains protons and neutrons.
What is the nucleus?
This is the "brain" of a computer that follows instructions and performs calculations.
What is the CPU (or Processor)?
Following the standard order of operations (PEMDAS), this is the final answer to the expression 10 + 2 * 5
What is 20?
What do we call the moon phase when the Moon is completely dark and not visible from Earth
New Moon
A roller coaster is at the top of the first hill (not moving) and then at the bottom of the hill (moving fast). Compare the potential energy and kinetic energy at these two points.
At the top: high PE, zero KE. At the bottom: low PE, high KE. Energy converted from potential to kinetic.
List the 3 states of matter in order from the lowest to the highest energy level.
What is solid, liquid, gas, (and plasmsa)
This is the "global highway" of interconnected computer networks that allows you to visit websites and send emails.
What is the Internet?
In the algebraic equation 4x - 5 = 15, this is the value of x.
What is 5?
Name all four outer planets (gas/ice giants) in order from the Sun.
Jupiter, Saturn, Uranus, Neptune
Two identical balls are dropped from the same height. Ball A is simply dropped, while Ball B is thrown horizontally. Ignoring air resistance, which ball hits the ground first and why?
They hit at the same time. Horizontal velocity doesn't affect vertical free fall motion - both experience the same gravitational acceleration downward.
This is the third element on the periodic table.
What is lithium?
Every device connected to a network has one of these unique "addresses," made of a string of numbers, so it can be identified.
What is an IP Address?
1/49
A lunar eclipse can only occur during which moon phase?
Full Moon
An object is dropped from rest and falls for 3 seconds. Using the equation d = ½gt², where g = 10 m/s², calculate how far it falls.
d = ½(10)(3²) = ½(10)(9) = 45 meters
This logarithmic scale measures how acidic or basic a solution is by relating the concentration of hydrogen ions in the solution.
What is pH?
To keep your secrets safe, computers use this process of "scrambling" data into a secret code that only the right key can unlock.
What is Encryption?
When you expand the binomial square (x + 4)2, this is the middle term of the resulting trinomial.
What is 8x
Our Moon always shows the same face to Earth (we never see the 'far side' from Earth). What is this phenomenon called, and why does it occur.
Tidal locking (or synchronous rotation). The Moon rotates once every ~27.3 days - the same time it takes to orbit Earth, which is why we always see the same side.
A 2 kg cart is released from rest at the top of a ramp that is 5 meters high. Using conservation of energy (PE = KE), calculate the cart's velocity at the bottom of the ramp. Use g = 10 m/s²
Answer: mgh = ½mv² → (2)(10)(5) = ½(2)v² → 100 = v² → v = 10 m/s
In a solution of saltwater, the salt is known by this term because it is the substance being dissolved.
What is the solute?
AI models like ChatGPT are known by this 3-word name because they are trained on massive amounts of text to predict the next word in a sentence.
What is a Large Language Model (LLM)?
These are the two positive numbers that solve the quadratic equation x2 - 5x + 6 = 0.
What are 2 and 3?
