• Mass and distance
• Mass and speed
• Velocity and distance

9 answers

The two variables that affect the gravitational force between two objects are mass and distance. Therefore, the correct answer is:

• Mass and distance

Which objects exert gravitational force? (1 point)
• Only objects that are close to each other exert a gravitational force
• Only large mass objects exert gravitational force on other objects.
• All objects exert a gravitational force on all other objects.
Only large mass objects exert gravitational force on objects near them.

The correct statement is:

All objects exert a gravitational force on all other objects.

This means that even small objects, although the force may be extremely weak compared to larger masses, do exert a gravitational force on each other.

Jackie, Bella, and Sam are discussing gravity. Bella says that they would weigh less on the moon than on the Earth because the moon exerts less gravity than the Earth. Sam says that their mass would be the same on the moon as it is on Earth. Jackie says that her weight and mass would stay the same if she went to the moon.
Who is correct?
(1 point)
• Bella is correct because the moon exerts less gravity than the Earth.
• Sam is correct because their mass would be the same on the moon
as it is on Earth.
Sam and Bella are BOTH correct because the moon exerts less
• gravity than the Earth AND their mass would be the same on the moon as it is on Earth.
• Jackie is correct because weight and mass do not change based on
the force of gravity.

The correct answer is:

Sam is correct because their mass would be the same on the moon as it is on Earth.

Bella is also correct in stating that they would weigh less on the moon due to the lower gravitational force. Jackie is incorrect because weight does change based on the gravitational force acting on an object. Therefore, the most appropriate answer considering the context is that Sam is correct, though it would also be accurate to say that Bella is correct about weight. However, the best choice based on the individual correctness presented is Sam.

A person states that the gravitational force between two objects depends upon the mass of the objects and the distance between them. Which argument best supports the person's statement? (1 point)
If the distance between two objects decreases, the gravitational force
• between the objects will decrease.
If the distance between two objects increases, the gravitational force between the objects will increase.
If the distance between two objects increases, the gravitational force between the objects will decrease.
If the distance between two objects decreases, the gravitational force
• between the objects will not change.

The argument that best supports the person's statement is:

If the distance between two objects increases, the gravitational force between the objects will decrease.

This aligns with the law of universal gravitation, which states that the gravitational force is inversely proportional to the square of the distance between the centers of two masses. Thus, as distance increases, the gravitational force decreases.

A student claims that the planets orbit the Sun because of gravitational force. Which statement best supports this claim?
(1 point)
• The Sun has more mass than the planets.
• Planets rotate on their axis faster than the Sun.
• The Sun was the first part of the solar system to form.
• Planets are farther from the center of the solar system.

The statement that best supports the claim that planets orbit the Sun because of gravitational force is:

The Sun has more mass than the planets.

This is because a greater mass exerts a stronger gravitational force, which is what keeps the planets in orbit around the Sun.
