The simple answer: about 490 Newtons (50 [kg] x 9.8 [m/s^2] = 490 [N]) by virtue of the relationship F=ma where F is force, m is mass and a is acceleration (in this case, the acceleration due to gravity).

Technically, your weight on earth depends on where on the earth's surface you are located. The reason being that the acceleration due to gravity (often denoted as little g) is not uniformly 9.80 m/s^2 at all places on the earth, due to factors such as altitude and air pressure, and less importantly, humidity and occasionally electric and magnetic disturbances, among others. However, a=9.80 m/s^2 is a good approximation for g (the English equivalent being approximately 32 ft/s^2).

Remember, this only works for weight on earth. Other planets or objects in space will have different accelerations due to gravity.

Since earth's gravity pulls at 1G, they would weight 50kg. While mass is constant, weight is not... conveniently (by design) earth's gravity is such that weight and mass should be equal on our own planet.

On Earth, gravity is about 9.8 newton/kilogram, so you can multiply the mass (in kilograms) by 9.8, to obtain the weight (in newton).

A person cannot weigh 50 kg since the metric unit of weight is a Newton, not a kg. Consequently the question makes no sense.

If a person weighs 120 kg on earth then what will he weigh on the moon?

kg (kilogram) is a measure of mass, not of weight. If a person has a mass of 120 kg on Earth, he will also have a mass of 120 kg on the Moon. His weight will change, his mass won't change.Mass is measured in kilograms and weight is measured in newtons..In daily life we use to say that this person having weight 120 kg but that is not correct .But in scientific language we must say that person is having a mass of 120 kg and his weightwould be calculated according to gravity of earth that is 9.8m/sec .Weight is actually the force ...so weight would beforce = acceleration * massweight = gravity * massweight =9.8 * 120=1176 newton(On earth)Gravity on moon is 1/6 of earth i.e. 9.8/6=1.64m/secAnd on moon also the mass would be 120 kg and the weight would beforce = acceleration * massweight = gravity * massweight = 1.64 * 120=196.8 newton (On Moon)As you can see the weight(force) on earth is 1176 newtonfor person having mass 120 kg and the weight(force) on moon is 196.8 newton.As the force on man on earth is 1176 newton so he would feel much more heavier.And the force on man on moon is 196.8 newton so he would feel lighter there.So the person having mass 120 kg will have more weight(force) on earth than on moon.Dont get confuse between mass and weight ...if you are 55 kg ...in daily use word we say our weight is 55 kg but that is not weight instead it's your mass and your weight is (55*9.8=539 newton) means you have mass 55 kg and weight 539 newton...if you still get problem do mail mevivianpeter2@gmail.comI m ready to help you
