Final J-Sci Question ….
Forces & Energy $100
Q: Newton’s Law of Inertia states that
an object in motion will stay in motion
and an object at rest will stay at rest
unless …
A. it is round.
B. it is acted on by an outside force.
And the answer is ….
Forces & Energy $100
Answer:
B. it is acted on by an outside force.
Forces & Energy $200
Q:
What do we need to know to calculate
the amount of force with which a
moving bowling ball hits the bowling
pins?
And the answer is ….
Forces & Energy $200
Answer:
You need to know the mass of the
bowling ball and the speed at which
it is moving.
Force = mass x acceleration
Select the bowling ball!
Forces & Energy $300
Question:
Burning wood is an example of a
_____________ reaction.
A. endothermic
B. exothermic
And the answer is ….
Forces & Energy $300
Answer
B. Exothermic
Burning wood gives off heat.
Forces & Energy $400
Question:
Describe the energy transfer that
takes place when a roller coaster
train is pulled up the first hill, and
then rolls over the hill to the bottom
of the other side.
And the answer is ….
Forces & Energy $400
Answer The potential energy
increased as the train is pulled up
the hill. The energy transfers to
kinetic energy as the train rolls over
the top and down the other side.
Forces & Energy $500
Question: A box is sliding down an
inclined plane (a slope). What effect
does the surface material of the
plane have on the speed? What
could you do to increase the speed of
the box?
And the answer is ….
Forces & Energy $500
Answer: To increase speed, you need
to decrease friction. Ways to do this
include:
• Make the surface of the slope less
rough (it would slide faster on ice
than on gravel).
• Add a viscous liquid (an oil, for
example) to the surface.

each parent?
And the answer is ….
Life Science $500
Answer:
Each parent must have at least one
allele for the recessive trait in order
for it to be the phenotype of the
offspring.

atomic number, the atomic symbol,
and the atomic mass in the picture
below:
6
C
12.01
And the answer is ….
Chemistry $200
A:
The atomic number is 6 (on top), the
atomic mass is 12.01 (on bottom),
and the atomic symbol is C (in
center).
6
C
12.01
Chemistry $300
Q:
Part A: When valence electrons are
transferred from one atom to
another, what kind of bond is
formed?
Part B: When atoms share valence
electrons, what kind of bond is
formed?
And the answer is ….
Chemistry $300
A:
Part A: Ionic bonds
Part B: Covalent bonds.
Chemistry $400
Q:
What combination of reactants is
likely to form an ionic bond?
And the answer is ….
Chemistry $400
A:
A reaction between an acid and a base
is likely to form an ionic bond.
Chemistry $500
Q:
Why are noble gases unlikely to
combine with other substances?
And the answer is ….
Chemistry $500
A:
Noble gases are unlikely to combine
with other substances because they
have a full outer shell of electrons.
This makes them very stable.
Earth/Space Science $100
Question: Is the solar system
heliocentric or geocentric?
A. Heliocentric: Sun is in center.
B. Geocentric: Earth is in center.
C. Heliocentric: Earth is in center.
D. Geocentric: Sun is in center.
And the answer is ….
Earth/Space Science $100
Answer:
A. Heliocentric: Sun is in the
center.
Earth/Space Science $200
