Force and Kinematics
What is the difference between speed and velocity?
Velocity measures speed IN A SPECIFIC DIRECTION
What is the distance between 2 crests on a wave called? (Think about what makes UV waves different from Infrared Radiation waves)
Wavelength
What is the difference between a solar and lunar eclipse?
In a solar eclipse, the sun's light is obscured by the moon from getting to the Earth. In a lunar eclipse, the sun's light is obscured by the Earth from getting to the moon.
What is one thing that can make a gravitational force greater?
more mass or less distance between objects
How many units are on the science NJSLA?
4 total, 2 units/day
Define acceleration.
Acceleration is the increase or decrease in velocity over a given period of time.
Which of the following wave types is not on the electromagnetic spectrum:
a. radio waves
b. positron waves
c. visible light waves
d. X-ray waves
e. none of the above
b. positron waves
What is the difference between revolution and rotation?
Revolution - objects moving around other objects
Rotation - objects spinning around
What is the difference between weight and mass?
Mass is something intrinsic to you, weight is dependent on the amount of gravity that you are experiencing.
Who is the only person that can touch NJSLA testing materials?
Your teacher
What is the equation for force (Newton's 2nd Law)?
Force = mass x acceleration
What is the name of the chicken in Surf's Up?
Joe
weight
What is the acceleration due to gravity on earth? (in meters per second squared)
9.8 m/s2
What is relative dating when determining the age of fossils?
Comparing different layers of the earth where the fossils were found. The deeper the layer, the older the fossil.
Why does my hand hurt when I slam it on the desk (think about Newton's Laws)?
Newton's Third Law: Every Action has an Equal and Opposite Reaction.
What are the highest and lowest energy waves on the electromagnetic spectrum?
Highest: Gamma Rays
Lowest: Radio Waves
What are moon phases caused by?
Moon phases are caused by the moon's revolution around the Earth - the bright and dark side of the moon are shown at different angles.
What is a word for Newton's 1st Law?
an object in motion stays in motion unless acted on by an opposing force.
inertia
Which of the following topics WILL be tested on the science NJSLA:
a. Ecosystems
b. Body Systems and Functions
c. Graphical Analysis
d. Genes and heritability
e. All of the above
e. All of the above
What would have a greater force? A bumblebee moving at an acceleration of 1 m/s2 or a bowling ball moving at a constant acceleration.
The bumblebee
What type of electromagnetic waves get trapped in our atmosphere by carbon dioxide molecules?
Infrared
How many days between full moons?
29-30 days
What object in our solar system provides a gravitational pull to Jupiter and keeps it in orbit?
the sun
What is the difference between dominant and recessive genes?
Dominant genes will always be expressed, recessive genes will only be expressed in the absence of dominant genes.
