What is an object's weight?

• The amount of matter in an object

• The force that attracts all objects toward each other

• The tendency of an object to resist a change in motion

• The force of gravity on an object

What is inertia?

• The amount of matter in an object

• The force that holds the moon in orbit

• The tendency of an object to resist a change in motion

• The force of gravity on an object

What is Newton's first law of motion?

• An object at rest will stay at rest and an object in motion will stay in motion with a constant speed and direction unless acted on by a force

• Every object in the universe attracts every other object

• The force that pulls an apple to the ground also pulls the moon toward Earth

• The strength of gravity depends on the masses of the objects and the distance between them

Why doesn't Earth fall into the sun?

• Because of inertia

• Because of gravity

• Because of the moon's orbit

• Because of the force of motion

How would the force of gravity change if the distance between two objects decreased?

• The force of gravity would increase

• The force of gravity would decrease

• The force of gravity would remain the same

• The force of gravity would become zero

What is the Earth's orbit?

• A straight path around the Sun

• A curved path around the Sun

• A circular path around the Sun

• A spiral path around the Sun
