Which of the following data would support the claim that the gravitational force between objects depends on mass?

• An object's weight can change depending on where it is on Earth.

• The further a planet is away from the sun, the smaller the gravitational force.

The Sun is much more massive than the Earth and has much more gravitational force. Why does the Sun not pull us from the Earth?

• The Sun's gravitational force does not effect humans.

• The Earth is closer to us.

• The moon is closer to us and blocks the force of gravity from the sun.

• The Sun is too massive.

Luke was using a simulator to find out how much he would weigh on different planets. he recorded his data in the table above. Explain why Luke's weight is so different on each planet.

• Luke's mass changes from planet to planet.

• Each planet's gravitational force exerted on Luke is different.

• Luke made an error entering information on the simulation.

• He changed his diet from planet to planet.
