Question

An object weighs 985 N on Earth's surface. The acceleration due to gravity on the moon is 1.62 m/s2. What is the object's weight on the moon?

Answer 1

Using the formula F=ma, where:

F = Force (N)

m = mass (g)

a = acceleration (m/s^2)

Now, since we have Force already, and we need mass, we need to rearrange the formula:

m = F/a

Now, plug in your values:

m = (985)/(1.62)

m = 608.02 kg

Answer 2

Answer : The weight of object on the moon is
`162.81\ N`

Explanation :

It is given that,

Weight of an object on earth, W = 985 N

Acceleration due to gravity on moon,
`a=1.62\ m/s^2`

We know that,

W = mg

where

W is the weight of an object on earth

m is the mass of the object

g is acceleration due to gravity.

`m=(F)/(g)`

`m=(985\ N)/(9.8\ m/s^2)`
`\because (g=9.8\ m/s^2\ on\ earth )`

`m=100.5\ kg`

We have to find the object's weight on the moon

`W=mg'`

Where

g' is the acceleration due to gravity on moon

`W'=100.5\ kg* 1.62\ m/s^2`

`W'=162.81\ N`

Object's weight on the moon is 162.81 kg.
