The force of gravity on the surface of Mercury is much less than on Earth. A rock has a weight of 100 newtons on Earth. What do you know about the weight of the rock on Mercury?

• The rock will weigh exactly 100 newtons.

• The rock will weigh more than 100 newtons.

• The rock will weigh less than 100 newtons.

• There is not enough information to know if the rock weighs the same, more, or less on Mercury.

A chair has a mass of 10 kilograms on Earth. What is the mass of the chair on Mercury?

• 10 kilograms

• more than 10 kilograms

• less than 10 kilograms

• not enough information

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

• The gravitational force gets weaker as objects get farther apart.

• The graviational force only pulls on objects.

• The gravitational force is greater on more massive planets.

• The graviational force is only attractive.

When a satellite is sent into orbit, what factor(s) keep it from crashing down into the planetary body?

• The planet's magnetic force repels the satellite from the planet.

• The applied force of thrust ONLY, keeping the satellite moving forward.

• The combination of an object's inertia (forward motion) and gravity.

• Satellites do not orbit a planet they only pass near planets on their journey through space

If each object has the same mass, which pair has the strongest gravitational attraction?

• The first, because it appears to weigh the most.
• The first, because the arrows are thickest.
• The  second, because it has an even balance of weight and distance.
• The first, because the objects are closest together.
