As the distance between two objects increases, the force of gravity between them decreases.

• True

• False

The gravitational interaction is caused by

• Earth's magnetic field.

• Earth's rotation.

• Earth's atmosphere.

• The interaction between two masses

Two people are sitting near each other in the classroom. There is a gravitational interaction

• between the two people that causes them to move toward each other.

• only between the earth and each person. The two people do not have a gravitational interaction between them.

• Two people are sitting near each other in the classroom. There is a gravitational interaction

• between the two people, but you don't notice it because it is so small.

Weight is another word for

• the interaction between an object and a planet's rotation.

• the mass of an object.

• the force exerted by a planet on an object.

• the interaction between an object and a planet's rotation.

Imagine you throw a ball up in the air. Assume there is no drag interaction. As the ball moves upward there

• is the upward force from the hand even though it no longer touching the ball.

• is a downward force exerted on the ball by the Earth.

• is an upward force exerted on the ball by the Earth.

• are no forces acting on the ball.

The variables that affect the gravitational interaction between two objects are:

• masses and directions of motions of the objects.

• masses and speeds of the objects.

• masses and distances between the objects.

• distance between and speeds of the objects.

As a space ship of constant mass moves farther away from Earth, the strength of the gravitational interaction between the Earth and the space craft

• stays the same.

• increases.

• there is not enough information to answer.

• decreases
