What force is the gravity at the surface of mars?

Answer 1

It's about 38% of the strength of Earth's surface gravity.

Answer 2

0.376 times Earth's surface gravity, around 3.687 newtons per kilogram. Because Mars is so much smaller and less dense than Earth, the force due to gravity at the Martian surface is only about 38 percent of that on Earth. Thus, a person standing on Mars would feel as if his or her weight had decreased by 62 percent. And if that person dropped a rock, the rock would fall to the surface more slowly than the same rock would fall to Earth.

The Surface Gravitational Force of Planet

= Mass (relative to the Earth) x (Radius of the Earth)² x 10÷ (Radius of the Planet)²

where the surface gravitational force for the Earth = 10 N/kg.

For Mars, the surface gravitational force for Mars = 0.10 x (6400)²x 10÷(3400)²

Surface gravitational force for Mars = 3.5 N/kg
The equatorial gravity at the surface of Mars is 0.376 that of Earth.
3.711 m/s²

Answer 3

The force of gravity between Mars and an object on its surface depends on both of

their masses, so it's impossible to predict the force without knowing what object

we're talking about.

We do know that the acceleration of gravity on the surface of Mars is 3.7 meters per second2

for any object, compared with 9.8 m/s2 on earth. So we're able to predict that whatever the

object happens to weigh on earth, it'll weigh 62% less than that on Mars.

That "weight" is the "force of gravity" that you're asking about.

Answer 4

The force of gravity depends on the mass of the object being forced,

so it's different for different objects.

The acceleration of gravity on the surface oif Mars is 3.71 m/s2 .

That's about 0.38 of its value on the Earth's surface.

Answer 5

The FORCE of gravity will also depend on the mass: weight (which is the force of gravity) = mass x (gravitational field).The gravitational field on Mars's surface is about 3.7 meters / second square = 3.7 newton / kilogram. For comparison, on Earth's surface, the gravitational field is about 9.8 newton / kilogram.
