SPI 0807.12.4 (Mass and
Weight)
The
space shuttle consisted of three main components: (1) A winged orbiter, (2) A large external fuel
tank, and (3) two booster rockets (see diagrams 1 and 2 above.)
After the shuttle blasted off, the
external tank and the two booster rockets were jettisoned. This significantly reduced the mass of the
spacecraft.
As the mass decreased, what happened to shuttle’s
weight?
a. | As the mass of the spacecraft increased, the space shuttle weighed
more. | b. | As the mass of the spacecraft decreased, the space shuttle weighed
less. | c. | As the mass decreased, the shuttle weighed more due to an increase in
gravity. | d. | The shuttle’s weight remained constant regardless of the mass of the
spacecraft. |

Which process is most suitable for the direct measurement of
mass?
a. | using a balance and
expressing the results in kilograms | b. | using a barometer and expressing the results in pounds per square
inch | c. | using an electronic scale and expressing the results in newtons per
meter | d. | using a spring scale and expressing the results in
ounces |

Which section of this Venn
diagram would go with the following statement?
Statement: “Changes from planet to
planet.”
a. | Section 2: Weight | c. | Section 4: Mass | b. | Section 1:

SPI 0807.12.4 (Mass and Weight)
Which statement correctly describes the measurement of an
object in units of grams and newtons?
a. | Both grams and newtons are
measures of the amounts of matter that make up an object. | b. | Grams are a measure of the amount of matter that
make up an object, and newtons are a measure of the force of gravity acting on an
object. | c. | Both grams and newtons are measures of the forces of gravity acting on an
object. | d. | Grams are a measure of the force of gravity acting on an object, and newtons
are a measure of the amount of matter that make up an
object. |

| Your NASA rocket is ready for lift off from the launch pad.
Your cargo includes a robot called the Venus Atmospheric Explorer (V.A.E.)
|
V.A.E. 
Mass: 730
kilograms
Weight: 7082 Newtons | | | |
If you measured the
robot’s mass on Earth, and then you measured it again in orbit about Venus, what would you
discover?
a. | You will notice an increase in mass since Venus is
closer to the sun than Earth. | b. | You will notice
that the robot’s mass has decreased due to less gravity on Venus. | c. | You will notice that the robot’s volume has greatly increased since
leaving Earth. | d. | You will observe
that the robot’s mass is unchanged. It is still 730
kilograms. |

SPI 0807.12.4 (Mass and
Weight)
How does mass affect gravitational force?
a. | Gravitational force between objects does not depend on their
masses. | b. | The gravity of an object increases as the masses of the objects
decrease. | c. | Gravitational force increases as the masses of the objects
increase. | d. | The gravity of an object decreases as the masses of the objects
increase. |

Lunar Moduel | Saturn V-Apollo
Spacecraft | Command
Module | | | | | | |
In 1969 astronauts
first traveled to the Moon in the Saturn-5/Apollo spacecraft. At a height of 111 meters and with a
mass of 2,970, 000 kilograms, it was the most powerful rocket ship ever built. The Saturn-5 was a
three-stage rocket which jettisoned sections as it exited Earth’s atmosphere, and only the
Lunar Module and Command Module actually traveled all the way to the Moon.
When the
astronauts maneuvered into the Moon’s orbit, the mass of the spacecraft was greatly reduced
down to only 29, 890 kilograms.
How did the mass of the spacecraft change from Earth to the
Moon?
a. | The Moon has less gravity than the Earth, therefore the spacecraft had less
mass. | b. | Spacecraft sections were discarded thus reducing the
amount of matter and mass | c. | Solar wind destroyed nearly 75 percent of the
spacecraft on the way to the Moon | d. | The spacecraft weighed much less on the Moon
due to the Moon’s lower gravity. |

a. | double pan balance | c. | spring
scale | b. | simple lever | d. | triple beam
balance |

SPI 0807.12.4 (Mass and
Weight)
In which of these
situations will an object become less massive?
a. | Matter is removed from the
object. | b. | The object is measured on a scale instead of a
balance. | c. | Heat changes the physical state of the
object. | d. | The object is weighed on the moon instead of on
Earth. |
