Atoms & Molecules
The smallest building block which has specific characteristics of a substance.
What is an atom?
The force when two things rub together.
What is friction?
Whenever there is a force acting on something in one direction, another force of the same size is acting on it in ____________.
What is "the opposite direction?"
The force which keeps the moon orbiting around the earth, and the force which causes high and low tides.
What is gravity?
I am the world's fastest diving bird.
What is a a peregrine falcon?
The distance something travels is the product of it's speed and the length of ________ which it travels.
What is time?
A substance that has only one type of atom bonded together
What is an element?
The term that describes how fast something is moving in a specific direction.
What is velocity?
Objects resist changing velocity on their own. They are said to have __________.
What is inertia?
The force that slows things down as air rubs against it.
What is air resistance?
I am a nocturnal marsupial found throughout much of North America.
What is an Opossum? (or "A Virginia Opossum")
A Great White Shark bites down with 18,000 Newtons (N) of force. If it bites down on 2 square meters of sea lion, it puts this pressure on the sea lion's body (in Newtons/m2).
What is 9,000 N/m2?
What it is made when two or more atoms bond together (can be the SAME atoms or DIFFERENT atoms).
What is a molecule?
A force that pulls things towards the center of a circle.
What is centripetal force?
The equation which describes the principle that how much force you need to make something accelerate (increase its velocity) depends on its mass.
F= m x a
Force=mass x acceleration
The Daily Double

I am a sea-faring mammal, I like to play in the waves, and I use echolocation to "see"
What is a whale (or dolphin)?
If the apple has a density of 0.96g/cm3, and it diplaces 1.92 liters of water, what is its mass?
What is 2g?

In physics, you are doing "work" when you use a force to _______something.
What is move?
Ultrasound waves, which are a higher frequency than the human ear can hear, were recently used to create a video picture from the abdomen of this person.
Who is Auntie Kristen?
This animal will not die even if it hits the ground at its terminal velocity
What is the squirrel?
The amount of work you do if you use a force of 2 N to lift Nala 1m into the back of the car to go to the vet.
What is 2 Joules (J)?
The positively charged particle found in the nucleus (center) of an atom.
What is a proton?
This word describes or measures how forcefully something is moving in a particular direction.
What is momentum?
We measure the amount of work done in a units which are newton meters (Nm). They are also known as _________.
What are joules (J)?
Your mass on the moon is __________[less than, more than, or the same as] your mass on earth.
What is "the same as?"
I am one of the heaviest insects in the world, weighing 3x as much as a mouse. I live in New Zealand.
What is the Giant Weta?
You run down the stairs in 10 seconds and use 1,000J of energy. How much power you used (in Joules / sec, otherwise known as Watts).
This facility took 20 years to build in Switzerland, and was built to try and recreate a "Big Bang," in search for a tiny piece of matter physicists thought existed (Higgs boson). The work that went into this formed the basis for creating the World-wide-web
What is the Large Hadron Collider?
Force is measured in kg m/s2, a unit otherwise known as ____________.
What is the newton (N)?
Name four types of tools that make it easier to do work (in physics, these are known as "machines").
What are an incline plane, a wheel, a lever, a pulley, a screw, or a wedge? (any four answers)
The inertia you feel pushing you outwards as you spin in a circle.
What is centrifugal force?
I am a toxic because I have symbiotic bacteria living in my salivary glands which produce the toxin tetrodotoxin (TTX).
What is the blue-ringed octopus?
An impala is trying to outrun a cheetah. It increases its velocity from 0 meter/sec to 4 meters/second in two seconds. Its acceleration is _________ meters/second2.
What is "2" meters/second2?
