This change from one form of energy to another is called:
A. Energy transformation
B. Kinetic energy
C. Mechanical energy
D. Electrical energy
CORRECT ANSWER: A. Energy transformation
I put a Pop-Tart in the toaster. Electrical energy is transformed to thermal energy to
make my Pop-Tart hot. Based on the Law of Conservation of Energy, once my Pop-
Tart starts to cool, is energy lost?
A. Yes. All the energy was used in the conversion of energy.
B. No. Energy cannot be created or destroyed.
C. Yes. The Pop-Tart is no longer hot.
D. No. Energy can be created, but it cannot be destroyed
CORRECT ANSWER: B. No. Energy cannot be created or destroyed.
At a constant velocity, a 5kg bag of cement is pulled straight up a 7m wall. How much
work is done by the puller? (Gravitational pull is 9.8m/s2, W(J)=F(N)*D(m)
A. 343 m/s2
B. 343 N
C. 340 J
D. 343 J
CORRECT ANSWER: D. 343
, What are the three phases or states of matter?
A. Liquid, Gas, Ice
B. Liquid, Solid, Gas
C. Gas, liquid, Slippery
D. Liquid, Gas, hard
CORRECT ANSWER: B. Liquid, Solid, Gas
Iron+ Oxygen->Iron Oxide (Rust)
2Fe+30₂ -> Fe₂O₃
Iron Oxide, formed from Iron and Oxygen, is a new:

B. Atom
C. Compound
D. Solution
CORRECT ANSWER: C. Compound
A fish swims through the water by using its fins to push water backwards. Pushing
water backwards propels the fish forward through the water. This most nearly fits
which of Newton's Laws?
A. Newton's First Law: Force=mass (acceleration)
B. Newton's Second Law: objects in motion will stay in motion unless acted upon by a
force, objects at rest will stay at rest unless acted upon by a force
C. Newton's Third Law: for every action, there is an equal and opposite reaction.
CORRECT ANSWER: C. Newton's Third Law: For every action, there is an equal and
opposite reaction.
Researchers want to conduct a study using random sampling. What is random
sampling?
A. Individuals are randomly selected from the population. Every individual has the
same probability of being selected.
B. A control group is selected and every other individual is used for data.
C. The population is divided into subgroups. Each subgroup has several individuals
that are selected.
D. The population is divided into age groups and individuals are chosen at random
from within those age groups.
CORRECT ANSWER: A. Individuals are randomly selected from the population. Every
individual has the same probability of being selected.
