Flashcardizz: The Martian Part 3-Beat the Teacher

Front

What is the effect of Mars' gravity on weight?

Back

Mars has only 38% of Earth's gravity, meaning objects weigh significantly less on Mars than on Earth.

Front

How can mechanical advantage help in lifting heavy objects?

Back

Mechanical advantage allows a person to lift heavier objects by using tools or techniques that reduce the amount of force needed.

Front

What is a strategy for rationing food in a survival situation?

Back

Reducing daily intake, such as going from 3 rations per day to 1 ration every 3 days, can help stretch limited food supplies.

Front

What indicates successful colonization of a planet?

Back

The establishment of permanent settlements and the ability to grow crops are key indicators of successful colonization.

Front

Why is it acceptable to replace a damaged part with a lighter material?

Back

In a thin atmosphere like Mars', lighter materials can be used without significantly affecting performance due to reduced air resistance.

Front

What happens to the body during high G-forces?

Back

High G-forces, such as 12 G, can cause blood to pool in the feet, leading to dizziness or loss of consciousness.

Front

What is the significance of growing crops on another planet?

Back

Growing crops is a sign of sustainability and self-sufficiency, indicating that a colony can support itself.

Front

How does reduced gravity affect physical tasks?

Back

Reduced gravity makes it easier to lift heavy objects, as they weigh less than they do on Earth.

Front

What are the risks of dehydration in space missions?

Back

Dehydration can lead to serious health issues, including dizziness, fatigue, and impaired cognitive function.

Front

What role does infrastructure play in colonization?

Back

Infrastructure, such as buildings and roads, is essential for supporting a permanent human presence on another planet.
