Gravitational Forces

An astronaut way out in space is considered to be “weightless" This is because–

• his mass is so small relative to the earth that gravity doesn't affect him

• gravitational force decreases greatly over long distances

• gravitational force pushes objects away from each other at long distances

• objects far away from the earth have less mass

Which of the following claims supports the data shown?

• Gravitational forces are proportional to the masses of the two objects.

• Gravitational forces are strongest between objects with identical masses.

• Gravitational forces are weakest when one object is more massive than the other.

• Gravitational forces can never exceed an upper limit, regardless of the masses.

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.

• Gravitational force is stronger on more massive planets.

• A rocket can escape Earth's gravity by traveling at high speed.
