Answers
1
What are most satellites used for?
Illegal Activities
Scientific Research, Communicating, and Military Intelligence
Hacking the USA 2016 Elections
Artificial Camera Knowledge
2
What is force?
push or pull
the thing that happens when you drop an apple??
i don't really care enough to answer
the same thing a velocity and acceleration
3
How is force typically described?
by its motion
by its TikTok account
by its velocity and acceleration
by its strength and the direction in which it acts
4
What is friction?
Andrea hates germs.
the force that two objects exert when they rub against each other
i don't have a pet cat because it would eat my fishies
(the correct answer is the green button)
5
How much does one Newton approximately weigh?
the same as an iPhone 12
a small tomato
a big apple
a small lemon
6
BONUS : What song did Mrs. Jaworski sing for us in 6th grade when we learned about Physical Science?
"The Bill Nye Theme"
I can't remember...
"Pangea, Oh, Pangea"
"Take Me Home, Country Roads"
7
T/F : Newton's 3rd Law of Motion states that every action has an equal or opposite reaction.
True
False
8
What is the formula for momentum?
I already told you, I blame the cat!!
Momentum = Mass / Velocity
Momentum / Mass = Velocity
Momentum = Mass x Velocity
9
What is the difference between balanced and unbalanced forces?
both cause the object to start moving
both move the object in the same direction
both cancel out to equal zero
balanced means there is no change, unbalanced means there is change
10
T/F : Sliding friction occurs when you swim in a pool.
False
True
11
What is gravity?
the thing that keeps us alive
the thing that makes you jump on the moon
the force that pulls objects towards Earth
the thing that makes flowers not die in the spring
12
What is weight?
5, 280 pounds
you can gain it by eating too many cookies
force of gravity on a person
I don't know, talk to my doctor.
13
When you jump off of a plane to sky-dive, are you in permanent free fall?
yaaaaaaaasssss kweeeeeeen
nope.
HECK NAW
yes, i think?
14
T/F : When equal forces are exerted in opposite directions, the net force is zero.
True
False
15
T/F : The strength of a force is measured in Newtons.
True
False
16
T/F : You are at a party, but you have no friends, so you are standing in corner alone. That causes static friction.
False
True
17
What is the SI unit of mass?
miles
grams
minutes
kilogram
18
What is net force?
all of the forces divided
all of the forces combined
all of the forces added together
all of the forces multiplied
19
Which one is an example of static friction?
swimming in a pool
Mrs. Jaworski dancing
going to the fall dance
sledding down a snowy hill
20
T/F : Inertia is the tendency for an object to assist a change in motion.
False
True
21
T/F : Universal gravitation applies on Mars.
True
False
22
T/F : Centripetal force is any force that causes an object to move in a circular path.
True
False
23
Which one is a projectile?
a piece of chocolate
a ball lying on the grass
a pie being flung at someone's face
Pennywise the Dancing Clown
24
T/F : Newton's 3rd Law of Motion states that an object won't move unless something moves it first.
True
False
25
T/F : Air resistance is a type of fluid friction.
True
False
26
What is the formula for acceleration?
Acceleration = Net Force / Mass
Mass = Acceleration - Net Force
the cat was the one who committed the crime, not me!
Acceleration = Net Force x Mass
