# Why do we weigh differently on different planets?

## Why do we weigh differently on different planets?

This mass does not change when we change planets. However, if we went from Earth to Mars, our weight would change because Mars has less gravity than Earth. So, a small planet has less and larger planet has more gravity. Just like the planets, a person with more mass has more gravity and therefore weighs more.

## Why do heavier planets have more gravity?

Volume increases as a cube and surface area as a square, so even a slightly bigger planet would have much stronger gravity.

How does gravity affect weight on Earth?

In a stronger gravitational field a given mass will have a larger weight. If an object is nearer a centre of mass then r will be smaller so g will be larger. In that case the weight of the object will be larger.

### Why does weight change on different planets but mass does not?

Your mass doesn’t change on other planets, but the gravity and size of those planets affect how much you weigh. So, your weight depends upon the gravity of the planet and your weight keeps changing based on planet gravity. A small planet has less gravity and the larger planet has more gravity.

### Why do some planets have more gravity than others?

Originally Answered: What makes the gravity of Earth and other planets different? The gravity of a planet, or asteroid, or really anything, is related to its size (mass). Bigger planets have more gravity. The sun, the largest object in our solar system is huge compared to any of the planets and has an enormous gravity.

Does planet size affect gravity?

Gravity is the force that keeps planets in orbit around the Sun. Planets have measurable properties, such as size, mass, density, and composition. A planet’s size and mass determines its gravitational pull. A planet’s mass and size determines how strong its gravitational pull is.

## How does gravity affect weight and mass?

Weight refers to the gravity force of planets and other bodies in the Universe, and the effect that this has on objects. This means that for a given gravitational field strength, the greater the mass of the object, the greater its weight. Weight is a non-contact force because gravity exerts its force through a field.

## What affects the gravity on planets?

A planet’s size and mass determines its gravitational pull. A planet’s mass and size determines how strong its gravitational pull is.

What is the relationship between weight and gravity?

Your weight is a measure of the pull of gravity between you and the body (planet) you are standing. Every object in the universe with mass attracts every other object with mass. Your weight depends on the gravitational pull of the planet. So higher the gravity higher your weight.

### What does the gravity of a planet solely depend on?

Gravity of a planet solely depends on its mass. Gravity does not depend on size of the planet or its density. Gravity demands that the whole mass of the planet be concentrated at its very center. The center of mass and the center of gravity are also located there.

### What is the relationship between mass and weight on other planets?

That means you mass is constant and will remain the same. Your weight on any planets is a result of your mass, the strength of gravity on the planet and the distance you are from the center of the planet. Your weight is a measure of the pull of gravity between you and the body (planet) you are standing.

Why do we measure mass rather than weight on Earth?

That’s why scientists and engineers often measure an object’s mass —how much matter the object contains—rather than its weight. Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity.
