Imagine you are on a space mission. What does your weight measure in this context?

the gravitational pull of your body's mass.

how much mass your body contains.

Consider the following statements about the gravitational force between two apples falling from a tree. Which of these is NOT true?

If the mass of both apples increase, the gravitational force between them weakens.

Gravity pulls the two apples toward each other.

If the distance between the apples increases, the gravitational force between them weakens.

Neil Armstrong felt lighter on the moon than on earth because

c. moon's mass is equal to Earth

Why can Neil Armstrong jump and float a little while he was on the Moon during the Apollo mission?

Because the Moon's gravity is NOT that STRONG.

Because the Moon's gravity is VERY STRONG.

If you were to measure the amount of matter that makes up an apple, what would you be measuring?

You would be measuring how much MATTER makes up the apple.

You would be measuring how much GRAVITY is pulling the apple.

If you were to carry a 10kg bag, where would you feel the bag is heavier , on Earth or on the Moon?

The weight of the bag DOESN'T CHANGE

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 distance from the planet's center

The planet's mass and your inertia

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 studying Einstein's Theory of Gravitation. According to this theory, what does it state?

The gravitational field is like a warping of space-time, similar to how a heavy ball placed on a stretched sheet of rubber would cause it to warp.

Gravitational fields have no effect on nearby objects, like a ball thrown in the air would not come back down.

Gravitational fields are a warping of space distance, like a rubber band being stretched.

Gravitational field is smoothing out of the space time continuum, like a wrinkle being ironed out of a shirt.

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 decrease because the gravitational force decreases

It would increase because the gravitational force increases

It would decrease because the gravitational force increases

It would increase because the gravitational force decreases

Imagine you are an astronaut in space. You see a star and wonder how far it is. You remember that a light year is...

The distance light can travel in a year in space

The speed at which light travels in space

The time it takes for light from the sun to reach you in space

The number of years it takes for light to be emitted from a star

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

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

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
