IPC final exam review questions well
answered graded A+
electromagnetic, strong nuclear, weak nuclear, and gravitational - correct answer ✔✔What are
the four universal forces?
true - correct answer ✔✔True or false? Electromagnetic force is associated with charged
particles.
electric forces and magnetic forces - correct answer ✔✔Name the only two forces that can both
attract and repel.
repel; attract - correct answer ✔✔Objects with like charges ___________ one another, and
objects with opposite charges __________ one another.
strong nuclear force - correct answer ✔✔The force that holds particles in the nucleus together
is the _________________.
they're able to hold the protons together that electrically would repel each other - correct
answer ✔✔What evidence suggests that nuclear forces have a powerful force of attraction?
100 - correct answer ✔✔Over extremely short distances, approximately how many times
stronger is the strong nuclear force than the electric force of repulsion?
Strong-Strong/Weak-Weak - correct answer ✔✔Compare and contrast the strong and weak
nuclear forces.
,every object in the universe attracts every other object; anything that has mass has gravity -
correct answer ✔✔State Newton's law of universal gravitation.
mass; distance - correct answer ✔✔The gravitational force of attraction between two objects
depends on _____________ and ____________.
true - correct answer ✔✔True or false? Gravity is the weakest universal force, but it is the most
effective force over long distances.
stronger - correct answer ✔✔The sun's mass is much greater than the mass of Earth, so the
sun's gravitational force is much ____________ than that of Earth.
the moon's inertia and centripetal force from Earth produce the nearly circular path - correct
answer ✔✔Why does the moon orbit Earth in a nearly circular path?
true - correct answer ✔✔True or false? The gravitational pull of the
moon is the primary cause of Earth's ocean tides.
Both. If the altitude was low the answer would be true. If the altitude was high the answer
would be false. - correct answer ✔✔True or false? The pull of Earth's gravity can slow an
artificial satellite, causing it to lose altitude and fall from the sky.
a force of attraction - correct answer ✔✔Gravity
mass, distance, and inertia. - correct answer ✔✔Gravity between planets is determined by the
planet's _________, ___________, and ______________
decreases - correct answer ✔✔As distance increases the gravitational force ___________.
, increases. - correct answer ✔✔As mass increases the gravitational force ________

a center seeking force - correct answer ✔✔centripetal force
reference point - correct answer ✔✔Motion is measured relative to a _______________
_____________.
The passenger in the front seat. - correct answer ✔✔A passenger riding in the back seat of car
driving at a steady pace, is at rest relative to...
the object is at rest - correct answer ✔✔On a distance versus time graph, what does a
horizontal line mean?
constant speed - correct answer ✔✔If the speed of a car does not change The car is traveling at
_____________ ___________.
80 km - correct answer ✔✔If a cyclist travels 20km in half an hour, how far will she travel in 2
hours?
0.2km/min - correct answer ✔✔Coach O'Neal runs his first km in 5 minutes, his second km in 5
minutes, and his last two km in 10 minutes. What is his average speed?
opposite/different - correct answer ✔✔If a toy car is moving 10m/s east and a second toy car is
moving 10m/s west. The toy cars have the _________________ velocity.
total time - correct answer ✔✔Average speed equals total distance divided by...
