Imagine you are studying the planets in our solar system. What 2 factors would affect the force of gravity that you would feel if you were standing on the surface of one of these planets?

• The planet's mass and your inertia

• The planet's mass and your distance from the planet's center

• Your distance from the planet's center and your inertia

• The planet's mass and the force of gravity on the planet

Imagine you are an astronaut in space and you observe a star's mass contracting into an area so small and the gravitational force at the surface becoming so large that even light cannot escape the surface. What would you say the star has become?

• a black hole

• neutron star

• a pulsar

• a super Nova

Imagine you are standing on a weighing scale on Earth and suddenly Earth's mass gets cut in half. What would happen to your weight?

• It would increase because the gravitational force increases

• It would decrease because the gravitational force decreases

• It would decrease because the gravitational force increases

• It would increase because the gravitational force decreases

Imagine you are observing the night sky. Which best describes why you see the moon moving around the Earth, according to General Relativity?

• The Earth's gravitational force pulls on the moon, causing it to orbit

• The Earth's gravitational force pushes on the moon, causing it to orbit

• The moon orbits because it moves around the curvature in spacetime created by the Earth's mass

John just got a new puppy and named it Max. He is curious to know about the mass of Max. What is he essentially trying to measure?

• how much matter is present in Max

• how much weight is present in Max

• the amount Max compresses a spring on a scale

• none of the answers are correct

If a spaceship increases its mass by collecting space debris, the pull of gravity on it...

• Increases

• Decreases

• Stays the same
