Peter Yang · Answer 1

Weight = (mass) x (gravity)

= (60 kg) x (9.8 m/s²)

= 588 newtons

(about 132.3 pounds).

It makes no difference whether you're on top of the hill,

down in the valley, in school or at church. As long as you're

anywhere on Earth, the acceleration of gravity doesn't change

until a few decimal places later, and neither does your weight,

so knowing your potential energy doesn't tell us anything.
