Gravity on Earth

Which is the best explanation of the term "weight"?

• A large celestial body that revolves around a star.

• Measurement of the force of Earth's gravity pulling you down.

• A push or a pull.

• Attraction between two objects that is proportional to the masses of the objects.

The attraction between two objects with a strength that is proportional to the masses of the objects is called:

• Force

• Gravitational force

• Gravity

• Planet

The force that pulls two objects toward each other and is affected by mass and distance. The greater the mass of an object, the greater the attraction; the farther apart the objects, the weaker the attraction is called:

• Force

• Gravitational force

• Gravity

• Planet

How is weight different from mass?

• Weight is the measure of the pull of gravity on an object, and mass is the amount of matter in an object.

• Weight is the amount of matter in an object, and mass is the measure of the pull of gravity on an object.

• Weight is the measure of the pull of gravity on an object, and mass is the amount of space that an object fills.

• Weight and mass are no different from each other.

Which of the following statements is NOT true?

• The Sun has the greatest gravitational pull because it is the most massive object in our solar system.

• The Moon revolves around the Sun.

• The planets follow an orbital path around the Sun.

• Gravity holds our solar system in place.

What does the law of universal gravitation state?

• Distance between two objects that have mass has no effect on gravitational pull.

• As the distance between objects with mass increases, the gravitational pull between those objects decreases.

• As the distance between objects with mass decreases, the gravitational pull between those objects decreases.

• As the distance between objects with mass increases, the gravitational pull between those objects increases.
