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

Lunar Moduel | Saturn V-Apollo

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. | Spacecraft sections were discarded thus reducing the
amount of matter and mass | b. | The spacecraft weighed much less on the Moon
due to the Moon’s lower gravity. | c. | The Moon has less gravity than the Earth,
therefore the spacecraft had less mass. |

Which property of
an object will be different on the moon than it is on Earth?
|

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

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 decreased, the space shuttle weighed
less. | b. | As the mass decreased, the shuttle weighed more due to an increase in
gravity. | c. | As the mass of the spacecraft increased, the space shuttle weighed
more. |

SPI 0807.12.4 (Mass and
Weight)
Which of these is best used to measure weight in newtons?
a. | triple beam balance | b. | simple lever | c. | spring
scale |
|
|
|
7.
|
SPI 0807.12.4 (Mass and
Weight)
Which process is most suitable for the direct measurement of
mass?
a. | using a spring scale and
expressing the results in ounces | b. | using a barometer and expressing the results in pounds per square
inch | c. | using a balance and expressing the results in
kilograms |
|

SPI 0807.12.4 (Mass and
Weight)
| 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 observe that the robot’s mass is
unchanged. It is still 730 kilograms. | b. | You will notice
that the robot’s volume has greatly increased since leaving Earth. | c. | You will notice an increase in mass since Venus is closer to the sun than
Earth. |

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. | Both grams and newtons are measures of the forces
of gravity acting on an object. | c. | 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. |
