... Question: What is the weight of a 100 kg object? Answer: w = m x g = 100 kg x 10 m/s2 = 1000 N • One Newton is equal to 0.225 pounds (lb), so in these common units 1000 N = 225 lb • Often weights are given by the equivalent mass in kilograms, we would say that a 225 lb man “weighs” 100 kg; this is c ...

Artificial gravity

Artificial gravity is the theoretical increase or decrease of apparent gravity (g-force) by artificial means, particularly in space, but also on Earth. It can be practically achieved by the use of different forces, particularly the centripetal force and linear acceleration.The creation of artificial gravity is considered desirable for long-term space travel or habitation, for ease of mobility, for in-space fluid management, and to avoid the adverse long-term health effects of weightlessness.A number of methods for generating artificial gravity have been proposed, as well as an even larger number of science fiction approaches using both real and fictitious forces. Practical outer space applications of artificial gravity for humans have not yet been built and flown, principally due to the large size of the spacecraft required to produce centripetal acceleration.
