An astronaut has a mass of 85 kg. calculate his weight on earth and on the earth’s moon. (gmoon = 1.6 m/s). does his mass change when he goes from earth to its moon?

on earth = 833 N

on moon = 136 N

No

Explanation:

Weight = mass * gravitational acceleration

(Assume gravitational acceleration on earth = 9.8 ms⁻²)

Weight on Earth = 85 * 9.81

                           = 833 N

Weight on moon = 85 * 1.61

                           = 136 N

Weight depends on the gravitational acceleration . But mass is independent from it

Mass doesnt change when we move object to one planet to another planet though Gravitational acceleration is varying planet to planet

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
