Question

when is weight equal to mg?​

Answer 1

Answer:

vertical movement

Explanation:

weight or force =ma(Newton's second law)

when a body moves vertically in the line of gravity, a gravitational force is exerted on it by the earth. this gravitational force is due to the acceleration towards the surface of earth (gravity) g which is estimated to be 9.8m/s2 .

so weight or force is equal to mg when the body is in vertical movement.

Answer 2

• when we are on the surface of the earth, our weight is equal to 'mg' on earth.
