weight
We would call it the person or object's "weight" on that planet.
because it does
The force of gravity on a person or object at the surface of a planet is calculated by the product of the mass of the person or object and the gravitational constant acceleration for the planet. For Earth, the gravitational acceleration is 9.8 m / s^2.
weight
The acceleration of gravity on a planet determines how fast an object will fall when dropped, affecting the weight of objects on the surface. This acceleration also impacts the force needed for objects to stay grounded or lifted from the surface. Overall, gravity's acceleration is essential in understanding an object's behavior on the planet's surface.
The force of gravity on a person or object on the surface of a planet is called weight. It is the result of the gravitational attraction between the object and the planet. Weight is measured in units of force, such as newtons or pounds.
The weight of an object on the surface of a planet depends on ...-- The mass of the object.-- The mass of the planet.-- The distance between the center of the object and the centerof the planet, i.e. the planet's radius.
Weight
The importantidea here is a planet's "surface gravity". That's the measure of the planet's gravitational "pull"at its surface. The larger this number, the heavier the weight ofan object on the surface of the planet. For example, the "surface gravity" on Mars is only 38% of the Earth's. So, if you could be on the surface of Mars, your weight would be 38% of your weight on Earth.
-- In a reference book or on-line, look up the acceleration of gravity on the surface of that planet. -- Multiply the mass of the object by the acceleration of gravity in the place where the object is. The result is the object's weight in that place.
The distance between a planet and an object affects the gravitational force between them. That means the size of a planet affects the value of the "surface gravity" for that planet. The greater thedistance from the surface to the center of the planet, the smaller the gravity at the surface (for the same planet mass). An example is the fact that Mars and Mercury have almost exactly the same surface gravity. Mars has more mass than Mercury, but this is balancedby the fact that Mercury hasthe smaller radius.
-- The product of the masses of the planet and the object on its surface; -- The distance between their centers of mass ... roughly the planet's radius.
