Understanding Newton's Law of Gravity

What does Newton's Law of Gravity state about objects?

• Objects attract each other.

• Objects only attract if they are large.

• Objects have no interaction.

• Objects repel each other.

Why don't small objects like toys visibly move towards each other?

• They are repelling each other.

• The gravitational force is too small.

• They are fixed in place.

• They are too far apart.

What is the main reason people move towards Earth and not vice versa?

• People are lighter than air.

• Earth's mass is much larger.

• People are fixed to the ground.

• Earth repels people.

According to Newton's third law, what happens when a fly hits a car windshield?

• The force on the fly is greater.

• The force on the windshield is greater.

• The forces are equal.

• There is no force involved.

What two factors determine the gravitational force between two objects?

• Distance and speed

• Size and shape

• Mass and distance

• Mass and speed

How does distance affect the gravitational force between two objects?

• Distance has no effect.

• Greater distance decreases force.

• Distance only affects small objects.

• Greater distance increases force.

What is the role of the gravitational constant (G) in the gravitational force formula?

• It has no role.

• It increases the force.

• It decreases the force.

• It is a scaling factor.

What happens to the gravitational force if the mass of one object is very large?

• The force becomes negligible.

• The force becomes very large.

• The force becomes zero.

• The force remains unchanged.

Why is the gravitational force between a teddy bear and a person negligible?

• They are not in contact.

• The gravitational constant is too large.

• The masses are too small.

• The distance is too large.

What must be true for the gravitational force to be noticeable between two objects?

• The objects must be touching.

• The distance must be very large.

• One object must be very large.

• Both objects must be small.
