"Inertia" is the keyword for one of Newton's 3 Laws of Motion. Which of the three laws talks about Inertia and what does that law state?
Newton's 1st Law.
object at rest or in motion will stay that way unless an unbalanced force acts on the object
What is white light?
all the colors of visible combined.
What happens to material when you add thermal energy into it? (be detailed, what changes? what happens to the particles that make it?)
The temperature increases, and the particles that make up the material move faster.
The material may also go through a change of state. (melting, evaporating).
1.What force is applied to humans every single day?
gravity
Explain where a solid, liquid, or gas are in each of these scenerios:
liquid soda. gas bubbles.
solid ice cream until it melts
liquid gas, gas vapors.
Explain the difference between Speed and Velocity.
Provide an example of each.
Speed = Distance/Time
Velocity = Speed + Direction
Which property of an electromagnetic wave determines the level or amount of energy it carries? (this also determines what kind of electromagnetic wave it is)
wavelength
Upon seeing Mr. Bean, Rashanna says aloud "Dang! No Cap, He is Hot!". Scientifically speaking, what is she really talking about?
Since Mr. Bean is a human being and alive he gives off thermal energy (or inferred waves). And if he were to hold a thermometer in his hands the temperature reading on the thermometer would go up.
1.What is the difference between balanced and unbalanced forces?
balanced forces do not cause a change in motion
unbalanced forces cause a change in motion
1.Would your weight change if you were on the moon? Explain your answer.
yes your weight would change because the moons gravity is weaker and weight is a measurement of gravitational pull
Which object would have a LARGER gravitational force acting upon it?
A. Hot Air Balloon
B. Rock the size of a hot air balloon
C. A hotdog
D. Aerogel that is just slightly larger than the size of the hot air balloon.
B. The Rock the size of the air balloon, because the rock will have the most mass.
Explain what is happening to the light in the image
refraction. different wavelengths bend differently. all the colors of light get separated.
Give an example of something with a large amount of Gravitation PE.
Give an example of something with a large amount of Elastic PE.
(various answers)
Give an example of Newton's 3rd Law, and explain it.
various answers.... equal and opposite forces
1.Would your mass change if you were on Mars? Explain your answer.
no, because your mass measures how much material something is made out of and that does not change with gravity.
What is Newton's 2nd Law talk about and what is the formula for it?
F = M x A
Force = Mass x Acceleration
It states that the more mass something has the more force it takes to accelerate it.
Ex: A loaded semi truck has more mass than a bicycle, so it is a lot harder to push a loaded semi truck than it is to push a bicycle.
Compare & Contrast
Light waves vs Sound waves
sound needs a medium, light does not.
sound: faster in denser materials
light: faster in less dense materials
light = transverse wave
sound = longitudinal wave
1.The potential energy is the greatest at the beginning peak.
2.The potential energy is transforming into kinetic energy at the base of the slope.
Luke Skywalker, Darth Vader, Yoda, & Rey are all applying the force to the same object.
Rey applies 300N of force to the West.
Luke applies 300N of force to the West.
Darth Vader applies 600N of force to the East & 300N of force to the South.
Yoda applies 1000N of force to the North.
What is the net force and in which direction will the object accelerate?
700N North
List which states of matter each of these are in.
A = solid
B = liquid
C = gas
Describe the motion of the runner at points A, B, & C on the graph.
A = constant speed away from starting point
B = no motion
C = constant speed back to starting point
Draw the electromagnetic spectrum.
Where is the lowest frequency?
Where is the highest frequency?
Where is the longest wavelength?

You suddenly wake up falling from an airplane! As you are rapidly falling to your DOOM you think to yourself "Wow, I've never converted so much Gravitation PE before!"
What is the logic behind that statement?
(btw... it turns out you are actually skydiving with a professional who is connected to you from behind. You just passed out briefly from panic when you first jumped out of the plane. So when you were closer to the ground the skydiving professional opened the parachute and you landed safely. You escaped your doom for today. congrats!)
You are high above the ground so you have a lot of gravitational PE and as you fall you are converting that PE to KE.
Using the information from the image, explain what will happen, the net force, and why.
The forces are unbalanced so there will a change in motion.
The force going to the Left is greater than the force going to the right, so the cart will accelerate to the Left.
Because the difference between the two forces is 40N, the cart will go to the left with a net force of 40N.
Give me your best science joke.
