Gravitational Forces

Gravity is the force that attracts an object toward the center of a large body of mass. The table provides data on the pull of gravity on different planets compared to Earth. On which planet would an 85-kg person have the lowest weight?

• Mercury

• Mars

• Jupiter

• Neptune

Acceleration due to gravity on or near the surface of planet earth is 9.8 m/s/s.

• True

• False

A person will have more mass if they travel to another planet with a different amount of gravity.

• True

• False

The force of gravity acts on

• small objects on Earth.

• large objects on Earth.

• all objects on Earth.

• all objects.

• your mom.

Which statement best describes the relationship between the weight and mass of an object?

• If mass increases, weight will decrease.

• If mass increases, weight will increase.

• Doubling mass reduces weight by half.

• An increase in mass will not affect weight.

The gravitational pull on planet A is greater than on planet B. Which of the following best describes the mass and weight of an object that goes from planet A to planet B?

• The mass will be the same, but weight will change.

• The mass will change, but weight will be the same.

• Both the mass and the weight will change.

• The mass and weight will be the same on both planets.

Jennifer is explaining the difference between weight and mass to her little sister. In comparing the two, which of the following could Jennifer use to correctly describe the weight of an object?

• Weight is the same everywhere in space.

• Weight is how much matter is within an object.

• Weight is the amount of gravitational pull on an object.

• Weight is not impacted by the force of gravity.

The strength of the gravitational force between two objects depends on

• Mass and Matter

• Mass and Weight

• Mass and Distance

• Mass and Strength
