Q:

What is the force of gravity on Mars?

A:

Quick Answer

The force of gravity on the planet Mars is only about 38 percent as strong as that on Earth. Surface gravity on Mars is much weaker than that of Earth due to the planet's small size and relatively low mass.

Full Answer

Mars is the fourth planet from the Sun and the second smallest planet found in the solar system. Mars is much smaller than the Earth in regards to all the factors that determine the gravity of a planet. While Mars possesses less than half the surface gravity of the Earth, its gravity is still strong enough for the planet to maintain an atmosphere.

  • Q:

    What is the force of gravity on Earth?

    A:

    The force of gravity on Earth is approximately 9.8 m/s2. The exact gravitational force, which is described as the acceleration of gravity, differs based on latitude and altitude of a specific point on Earth. For example, gravity at the North Pole is 9.832 m/s2 and the gravity in New York is 9.803 m/s2.
