100
Explain inertia
the resistance of an object to change it's motion
(an object will continue doing what it is doing unless a force acts upon it)
100
Explain the mechanical energy
kinetic and potential energy together doing work
100
What evidence within rock layers helps with relative dating of species?
a. Mass extinction
b. Fossil record
c. The dinosaurs
b. The fossil record
100
the height of a wave is called
amplitude

How do you say Merry Christmas in Hawaiian?
Mele Kalikimaka
200
In Newton's third law, forces always come in
a. Speed
b. mass
c. pairs
pairs
(equal and opposite)

A ball is kicked over the goal post and then stops.
Explain the transfer of energy between the player's foot and the ball.
energy is transfered from the players foot to the football
200
In a rock layer, what would be the reason for a sudden disappearance of a species.
A mass extinction event.

On the electromagnetic spectrum, which waves have the longest wavelength and the least energy?
Radio Waves
200
In Home Alone 2, what city did Kevin get lost in?
New York
300
Name all three laws and tell what they are
First Law (interia)- Object in motion stays in motion (or in rest)
Second Law= Force = m x a
Third (action reaction, momentum)
300
What is a force
a push or pull
300
Explain the Law of Superposition
The oldest rock layers are found at the bottom of a fossil record
300
as wavelength decreases what happens to the frequency?
it increases, becomes stronger.

what famous musician grew up on a christmas tree farm in Tennessee
Taylor Swift

The man is pulling the box and it is moving at a constant speed, with NO FRICTION. What would happen to the Box if he let go of the rope?
AND
Which law does this demonstrate?
it would continue moving at the same constant speed
(newton's first law, inertia)
400
In the skate park lab, when did the skateboarder have the most kinetic energy
AND
what did adding friction to the ramp do to the speed?
at the bottom of the ramp.
Slowed it down.
400
Why was the crater in Mexico larger than the asteroid that formed it?
Because of the magnitude of the force during the impact. The mass and velocity created a large moutn of kinetic energy.
400
Where are the DSN center's located and why is important they are scattered around the world.
Australia, California, Spain
So as the world rotates, signals are not lost.
400
What item did Buddy the Elf eat at the doctor's office?
Cotton Balls
500
Name one other discovery of Sir Isaac Newton
Calculus
Gravity
Mirrors for telescopes
500
What is the net force? Which direction should it move?
AND
What happens if the net force is zero.
150 Newtons (right)
It will not move
500
In the DART mission, why did engineers increase the speed of an spacecraft before it hit the asteroid ?
Which of Newton's Laws can help explain this?
To gain momentum and force, enough to make an impact.
Newton's 2nd law- FORCE = Mass x acceleration
Newton's 3rd law- equal and opposite reaction
500
explain the difference between mechanical and electromagnetic waves
Mechanical- Require a medium (i.e. solid, liquid, gas in order to travel)
Electromagnetic- can travel in space (no medium required)
