Gravity Review

High and low tides are the regular pattern of rising and sinking ocean water levels. They are formed as a result of the gravitational forces of the moon and sun on Earth's oceans. The moon has a greater effect than the sun on the Earth's oceans. Why would the moon have a greater effect than the sun?

• The moon is not as hot as the sun

• The moon has less mass than the Earth

• The moon has less mass than the sun

• The moon is closer to Earth than the sun is

What is gravity?

• the force that pushes all objects toward Earth

• the force that pulls all objects toward one another

• a magnetic force that is strongest at Earth's poles

• a stream of charged particles from the sun to the Earth

Two objects have a certain gravitational force between them. What would happen if the mass of one of the objects suddenly increased?

• The mass of the other object would increase

• The distance between the objects would increase

• The gravitational force of the objects would remain constant

• The gravitational force between the two objects would increase

Venus has less mass than Earth. If a 50-gram object is taken from Earth to Venus then-

• The object's mass will be more than 50g

• The object's mass will be less than 50g

• The object's weight will be more

• The object's weight will be less

• Mercury

• Venus
