if a person weighs 120kg on earth, how much would they weigh in space
200N
THE ANSWER WILL BE 200 NEWTON/200N
To calculate how much a person would weigh in space, we need to understand the concept of weight and gravity.
Weight is the force exerted on an object due to gravity. On Earth, gravity pulls objects towards the center with a certain force. The weight of an object on Earth is determined by multiplying its mass by the acceleration due to gravity, which is approximately 9.8 meters per second squared (9.8 m/s²).
However, in space, the force of gravity is significantly weaker or absent altogether, depending on the distance from any massive objects. Astronauts in space experience weightlessness because there is no gravity pulling them down.
So, if a person weighs 120kg on Earth, it means that their weight is 120kg multiplied by the acceleration due to gravity (9.8 m/s²). Thus, their weight on Earth would be approximately 1,176 Newtons (N).
In space, where gravity is negligible or non-existent, the person's weight would be effectively zero. However, it's important to note that their mass remains the same regardless of the gravitational field. Mass is a measure of the amount of matter in an object and is typically expressed in kilograms (kg).
So, in summary, in space, the person would not weigh anything, but their mass would remain the same at 120kg.
