The mass of an object Is 45 kilograms. It's weight on earth is- - newtons, and it's weight on the moon is - -newtons. Gravitational force is 9.8m/s2 on earth and 1.6m/s2 on the moon

The weight of the object on earth = 441N

Weight of the object on moon = 72N

Explanation:

Weight of a body is the product of its mass and acceleration due to gravity. Acceleration due to gravity varies between planetary bodies. The acceleration due to gravity on earth is 9.8 m/s² while on moon is 1.6m/s² and it goes different for others too.

Weight = Mass * acceleration due to gravity

Weight (e) = weight on earth

Weight (m) = weight on moon

Weight (e) = 45 * 9.8 = 441N

Weight (m) = 45 * 1.6 = 72N

Weight of a body is measured in a unit called Newton (N)
