Question

Two objects of the same mass are on two different planets. Planet A has a force of gravity that is stronger than that of Planet B. How will the weights of the objects compare to each other?

A. The weights of the objects will be the same.

B. The weight of the object on planet A will be greater than the weight of the object on planet B.

C. The weight of the object on planet A will be less than the weight of the object on planet B.

D. This cannot be determined without knowing the actual mass of the objects.

Answer 1

Weight is the measure of the gravitational pull on an object

W = mg, where W is the weight, m is mass, and g is the gravitational constant (higher g = higher force of gravity)

m is the same for both objects. think about what happens to the W as g increases.

Answer 2

for W = mg

if g increases, W also increases

therefore, the weight of the object will be greater on the planet w/ the greater force of gravity

Answer 3

ok I think I get it, B is the final answer then?

thats because if the force of gravity increases, the weight will increase, right?

Answer 4

yup
