How much gravity an object has depends on it's

• weight

• speed

• momentum

• mass

• acceleration

When will gravity be the strongest?

• the further away you are from the object

• the closer you are to the object

• distance has nothing to do with gravity

• A

• B

• C

• D

Which statement is true?

• the moon's gravity has a greater effect on the Earth's tides because it is bigger

• the moon's gravity has a greater effect on the Earth's tides because it is closer

• the sun's gravity has a greater effect on the Earth's tides because it is bigger

• the moon's gravity has a greater effect on the Earth's tides because it is closer

Most space missions are

• manned

• unmanned

What is the most important reason orbiting space telescopes like Hubble and Kepler are able to send back images that we can't get from Earth bound telescopes?

• orbiting space telescopes can see further and deeper into space.

• orbiting space telescopes are significantly closer to the objects that they are trying to view

• Light from cities make it harder to see objects in space

• orbiting space telescopes do not have to look through the Earth's atmosphere so they get clearer imagines

You would weigh______________________ on Jupiter because Jupiter's ____________ is greater than Earth's and therefore the pull of gravity on your body is greater.

• more/mass

• more/volume

• less/mass

• less/volume
