Design a simple experiment to demonstrate Newton's Third Law using a balloon and a straw.

• Inflate the balloon, attach it to a straw on a string, and release it to observe the straw moving in the opposite direction.

• Inflate the balloon and let it float in the air.

• Attach the balloon to a straw and let it sit on a table.

• Inflate the balloon and pop it with a pin.

Construct an argument to support the claim that gravitational interactions depend on the masses of interacting objects.

• Larger masses exert a stronger gravitational pull, as seen in the attraction between Earth and the Moon.

• Gravitational interactions are the same regardless of mass.

• Only small masses experience gravitational interactions.

• Gravitational interactions are random and unpredictable.

What is the relationship between the mass of two objects and the gravitational force between them?

• The gravitational force is inversely proportional to the product of their masses.

• The gravitational force is directly proportional to their masses.
