How and why will my weight change if i took a trip to the moon

Due to gravitational force

We know that,

            weight (W) =  m. g  Newtons

            Where m = mass , in Kg

                        g = gravitational force (m/s²)

                           = 9.8 m/s (it is constant on earth)

         So, from equation we knew that Weight is proportional to the gravitational force assuming fixed mass.

      On the moon the gravitational force (g) is very less compared to the earth gravitational force, i.e., 1.62 m/s²

       Therefore from equation of weight W = m. g is very less by considering the gravitational force on moon.

So, obviously weight changes on moon due to gravitational pull

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
