Gravity vs Mass

Gravity is the force that attracts an object toward the center of large body of mass. The table provides data on the pull of gravity on different planets compared to Earth. On which planet would an 85-kg person have the lowest weight?

• Mercury

• Mars

• Jupiter

• Neptune

Why is the force of gravity on Earth stronger than on the moon?

• The Earth has more mass.

• The moon is closer to the Sun than the Earth.

• The Earth is closer to Jupiter.

• The moon has more mass.

What is the difference between mass and weight?

• Mass does not change no matter where it is in the universe, the weight of an object changes based on the gravitational force. An object will weigh more on earth than on the moon, because the earth has a greater gravitational pull than the moon.

• Mass does change no matter where it is in the universe, the weight of an object changes based on the gravitational force. An object will weigh more on earth than on the moon, because the earth has a greater gravitational pull than the moon.

• Mass does not change no matter where it is in the universe ,the weight of an object does not change either based on the gravitational force. An object will weigh more on earth than on the moon, because the earth has a greater gravitational pull than the moon.

• Mass does change no matter where it is in the universe, the weight of an object does not change based on the gravitational force. An object will weigh more on earth than on the moon, because the earth has a greater gravitational pull than the moon.

What is the correct equation for weight?

• W = m / g

• W = m + g

• W = m x g

• W = m - g

How would the mass of an object change if moved from Earth to the Moon?

• It would decrease

• It would increase

• It would become zero

• It would stay the same

Why do objects appear weightless on the International Space Station?

• There is no gravity in space

• The space station cancels out Earth's gravity

• Objects are in constant freefall around Earth

• Astronauts use special anti-gravity technology
