The statements are as follows:
1. True
2. True
3. True
4. False
6. The amount of matter in an object is its mass.
7. Gravity attracts all objects toward each other.
8. An object with greater mass is more difficult to stop or start.
9. The masses of two objects and their distance from each other determine the gravitational force between them.
10. The measure of the force of gravity on an object is the object's weight.
1. True
Newton's first law of inertia states that an object at rest will stay at rest and an object in motion will stay in motion unless acted on by an external force.
2. True
Inertia and gravity combine to keep Earth in orbit around the sun and the moon in orbit around Earth. Inertia helps to maintain the motion of objects in the absence of external forces.
3. True
Newton's law of universal gravitation states that every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
4. False (missing statement)
4. Earth's gravity pulls the moon inward.
The force of gravity between the Earth and the moon pulls the moon toward the Earth, creating its orbit.
