Gravity, Inertia, and Weight Exit Slip

What two factors affect the pull of gravity on an object? (choose ALL that are true)

• How far away an object is

• The mass of an object

• The name of the planet

• How many people are on the planet

If the force of gravity from the Sun were to suddenly disappear, Earth would ____

• Continue to travel in a straight path

• Continue to move in a curve around the Sun

• Continue to move in a curve, but the curve would be larger

• Stop moving completely

Why do planets have a circular shape to their orbit around the Sun?

• Gravity and Inertia combine to give them that shape

• Gravity from the Sun pulls the planets in towards the Sun in a circle

• Inertia pushes the planets in a circular path

You travel to the Moon. Which of the following is true? (choose ALL that are true)

• Your mass stays the same

• Your weight stays the same

• Your mass is different

• Your weight is different

When you travel to a planet, like Jupiter, where the force of gravity is greater than on Earth, _____

• You will "weigh more" than on Earth

• You will "weigh less" than on Earth

• You will have "less mass" than on Earth

• You will have "more mass" than on Earth

Because the force of gravity on the Moon is less than that on Earth, if you jump up with the same force, you will ______

• jump higher than on Earth

• jump shorter than on Earth

• jump the same height as on Earth

According to the formula "W=m×g," your weight is determined by _____ (choose ALL that are true)

• your mass

• the force of gravity

• your height

• your volume

A lunar lander weighs 500 kg. The force of gravity on the Moon is 1.6 m/s². What will the lunar lander weigh on the Moon?

• 800 N

• 500 N

• 1,000 N

• 312 N

You travel to two planets with different features. One planet is larger (more volume). One planet has more mass (made of more stuff). Which of the following is true?

• The planet with more mass will have more gravity

• The larger planet will have more gravity

• They will have the same gravity

• Neither planet will have gravity
