Understanding Newton's Law of Universal Gravitation

What is the primary reason objects attract each other according to Newton's law?

• They have similar shapes.

• They have mass.

• They are made of the same material.

• They are in close proximity.

What is the gravitational force between an object and Earth commonly known as?

• Mass

• Weight

• Density

• Volume

How does the weight of an object change if its mass doubles?

• The weight remains the same.

• The weight doubles.

• The weight halves.

• The weight triples.

In the apple experiment, why do both apples hit the ground at the same time?

• Both apples accelerate at the same rate.

• The small apple is heavier.

• The large apple is lighter.

• Both apples have the same mass.
