How does the gravity on Mars compare to Earth's gravity?

• Gravity on Mars is 75% of Earth's gravity.

• Gravity on Mars is double Earth's gravity.

• Gravity on Mars is about 38% of Earth's gravity.

• Gravity on Mars is the same as Earth's gravity.

Why is the gravity on Venus similar to Earth's gravity?

• Venus is closer to the Sun than Earth

• Venus has a stronger gravitational pull than Earth

Calculate the weight of a 50 kg object on Mercury (acceleration due to gravity on Mercury is 3.7 m/s^2).

• 100 N

• 370 N

• 50 N

• 185 N

If you weigh 60 kg on Earth, how much would you weigh on Mars (acceleration due to gravity on Mars is 3.7 m/s^2)?

• 22.695 kg

• 30 kg

• 45 kg

• 15.5 kg

Explain how the gravity on Mercury affects the movement of objects.

• Gravity on Mercury has no effect on the movement of objects.

• Objects on Mercury experience weaker gravity, causing them to weigh less and move more slowly.

• Objects on Mercury experience stronger gravity, causing them to weigh more and move faster.

• Objects on Mercury float due to the lack of gravity.

What is the gravitational pull like on Venus compared to Earth?

• No gravitational pull

• Equal to Earth

• Less than Earth

• Greater than Earth

Calculate the weight of a 70 kg object on Mars (acceleration due to gravity on Mars is 3.7 m/s^2).

• 400 N

• 259 N

• 320 N

• 180 N

How does the gravity on Venus impact the atmosphere of the planet?

• The gravity on Venus impacts the atmosphere by creating a strong magnetic field.

• The gravity on Venus impacts the atmosphere by allowing it to be retained and creating a strong greenhouse effect.

• The gravity on Venus impacts the atmosphere by causing hurricanes and tornadoes.

• The gravity on Venus impacts the atmosphere by reducing the temperature to extreme lows.

Discuss the differences in gravity between Mercury, Mars, and Venus.

• Venus has a gravity of 75% of Earth's gravity

• Mars has a gravity of 20% of Earth's gravity

• The gravity on Mercury is about 50% of Earth's gravity

• The gravity on Mercury is about 38% of Earth's gravity, on Mars it is about 38% of Earth's gravity, and on Venus it is about 91% of Earth's gravity.
