Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth’s gravity is what keeps you on the ground and what causes objects to fall. Gravity is what holds the planets in orbit around the Sun and what keeps the Moon in orbit around Earth. The closer you are to an object, the stronger its gravitational pull is. Gravity is what gives you weight. It is the force that pulls on all of the mass in your body.

As objects move away from the Earth, what gravitational change occurs and how does it impact the weight of an object?

• a. Gravitational pull would become stronger, and weight would increase.

• b. Gravitational pull would become stronger and weight would decrease.

• c. Gravitational pull would become weaker and weight would increase.

• d. Gravitational pull would become weaker and weight would decrease.

The following chart displays information about the planets in the solar system, based upon this, which of the following is true?

• a. Venus rotates far more slowly than Earth.

• b. Venus’s year is longer than Earth’s.

• c. Mercury is approximately twice the size of Earth.

• d. All of the above.
