Question

An astronaut who weighs 175 pounds on Earth goes to Mars, where the gravity is about a third of Earth's gravity. Which of the following statements is true about the astronaut's weight and mass on Mars?

The astronaut's weight would be the same, and their mass would be greater.

The astronaut's weight would be greater, and their mass would be the same.

The astronaut's weight would be smaller, and their mass would be smaller.

The astronaut's weight would be smaller, and their mass would be the same.

Answer 1

The astronaut's weight would be smaller, and their mass would be the same.

On Mars, the gravitational pull is weaker compared to Earth, so the astronaut would weigh less on Mars. However, the astronaut's mass, which is a measure of the amount of matter in their body, would remain the same regardless of the gravitational pull.
