What would happen to my weight if the mass of the Earth doubled?
Doubling the mass of the Earth would double your weight, since gravitational force is directly proportional to mass, but doubling the radius (which doubles if the diameter doubles) would decrease your weight by a factor of 1/4, since gravitational force is inversely proportional to the square of the radius.
How would my weight change if the mass of the Earth increased by 10\%?
As shown in the above graph, changing one of the masses results in change in force of gravity. In this case, if the earth’ mass goes up by 10\%, then the force of gravity on you, or your weight, will increase by the same amount, that is 10\%.
What would happen if we doubled the mass of the Earth?
If you doubled the earths mass and doubled its radius you would only weight half as much on the larger earth. Or gravity at the surface would be .5 of the earths gravity. If Earth’s mass doubled then the acceleration due to gravity, which we normally feel as 9.81 m/s 2, would also double.
What if the Earth were twice as Big?
Part 7: What if Earth were twice as big? If Earth’s diameter were doubled to about 16,000 miles, the planet’s mass would increase eight times, and the force of gravity on the planet would be twice as strong.
What would happen if the world doubled in size?
Humans and animals alike would grow bigger bones to support the extra weight, but our bodies would shrink under the increased pressure. Vegetation would evolve too, it would shrink to reducing the amount of energy needed to circulate water and vital nutrients. A potential bonus is that the world would be a whole lot warmer if it doubled in size.
What is the relationship between the weight and mass of Earth?
The weight and mass of Earth are directly proportional if nothing else changes. This means that if the mass of Earth tripled, your weight would triple. If the mass of Earth was reduced to half, your weight would reduce to half. Weight is also known as the force of gravity.
