Ok, so Earth pulls all things down at the same rate right? So why do we weigh differently? We should all weigh the same if we are on Earth?
- Earth pulls equally on each kilogram. If you have more kilograms than me, then the pulls add up to more for you.10
- People and objects have different masses. Weight W=mg
g=9.8 m/sec^2. It is the same for every thing on earth. But mass m is different for different objects.20
- The mass of the Earth is the same, but your distance from the center of the Earth is different, and your mass is different from that of my great grandkids. The formula says your weight is proportional to your mass, the Earth's mass, and inversly proportional to the square of the distance from the center of the Earth to you. Big difference is the differences between our masses.11
- Gravity is a theory not a fact look into flat planet theory dont knock it until you realize that it doesnt change the earths makeup if its flat is just puts the North Pole (witch really isnt the north cause there is no top to this flat surface) in the center of the earth and Antarctica as a rim of ice around the edge of the earth and the middle inbetween Antarctica and the "North Pole" would be the equater the middle of two cold places would be the warmest. No we are not going in circles around the globe we are going in circles around this flat round surface13
- We all are attracted toward the earth's CoM by the same acceleration g ....since masses are different one from another , then Weight = m*g differs from one to another10
- Earth pulls all things at the same rate, but that rate is applied to the mass of the object. So more mass, the more the Earth pulls on it.
If you have a mass of 2 kg, the Earth pulls on it more strongly than a mass of 1 gram.00
- earth dont "pull" anything - earth creates a distortion in space/time with the earth at the centre of the distortion
space/time then "pushes" things towards the centre of the distortion (where the earth is)00
- Gravitational attraction (between two objects) depends on the masses of both objects, and the distance between them.: F = Gm1m2/r2.
- Weight is a force:
force = mass * acceleration
Where for weight, the acceleration due to gravity is about 9.81 meters per square second.
weight = (mass in kilograms) * (9.81 meters per square second)
= ____ Newtons.
So if somebody drops a half kilogram weight on you from a same height, it would hurt less than a 5 kilogram weight from the same height, although they fall at the same acceleration. But a feather falls not at the same rate because it gets picked up pressure undercurrents in the wind.10
- In looking at a skinny person and at an obese person you might understand that there is far more "substance" in the obese person. That "substance" is called "Mass" in scientific terms.10
- Becuase Newton's law of gravitation: the gravitational force is proportional to the product of the mass of both objects. So if someone on Earth has twice the mass of another person, that person feels twice the gravitational pull.40

- Is infrared harmful to human body?
- If 'infinity' is for real, isn't it possible to go the other way, as in just 1 grain of our sand may contain millions of universe?
- How deep could an ocean get without breaking any of the laws of physics of the known observed understood universe?
- Is it true that we are all constantly being watched by sattelittes and if you kill someone on the streets you will get caught by the camera?
