Question

At the surface (if there is one) of Jupiter the acceleration due to gravity is about 3 times the acceleration due to gravity at the Earth's surface. How much would a 100 kg rock weigh on Jupiter?

why?

Answer 1

it would weigh the same. measurement of mass is irrespective of the gravitational acceleration on it. Its weight changes with the change in gravitational force.

Answer 2

Wouldn't that be for mass? Not weight?

Answer 3

idk like gravitational weight or something.

Answer 4

weight is the product of mass of a body and the gravitaional acceleration on it.

Answer 5

yes and the acceleration due to gravity is 3x? on jupiter? how would that make it the same weight

Answer 6

not the same weight. when say, " how much does that weigh?" you mean to talk about the mass

Answer 7

hmmm i'm unsure. it's for a take home quiz so :/

Answer 8

@ramkrishna like to say something?

Answer 9

haha

Answer 10

@chand Weigh mean not mass it is

weigh=mass * acc. due to gravity

acc. due to gravity on Jupiter = 9.8*3

Answer 11

so i would do 9.8*3*100?

Answer 13

@aidanp95 yes.

Answer 14

are u sur that acceleration gravity on jupiter is greater than on the earth?

Answer 15

Thank you sirs @ramkrishna @chand

Answer 16

@aidanp95 owe it to ramakrishna. he corrected me. Sorry for the wrong answer and thanks for correcting me.

Answer 17

yes. acc. due to gravity on Jupiter is approx. 26

Answer 18

@chand its okay you tried haha i was confused too

Answer 19

Let's make things simple:

If gE =10 N/kg and gJ = 30 N/kg, then a 100 kg rock would weigh 1000 N on Earth and 3000 N on Jupiter.
