meteorite lands on earth, weight 65N, wats its mass, and wat would its weight be if landed on the moon instead

Question

(where g =1.6N/Kg) in a formular please,,,,I cant believe this,,,im still not getting it in my head...cheers guys.

Answer 1

force=mass x acceleration(a)
weight=mass x acceleration due to gravity(g)

weight = force
So unit of weight is newton(N).

Value of acceleration due to gravity(g) on the earth is 9.8 m/s^2

Value of acceleration due to gravity(g) on the moon is 1/6th value acceleration due to gravity(g) on the earth and that is 9.8/6=1.6 m/s^2

Mass of a material remains same every where.
Weight of meteorite on moon is 65/6=10.83N

Answer 2

W = mg
where
W is weight
m is mass
g is the acceleration due to gravity

m = W/g
m=65 N / 9.8 m/s^2
m = 6.632653061 kg.

that's the mass of the meteorite.


To find its weight on moon, simply divide its weight on earth by 6 because the acceleration due to gravity of the moon is just one-sixth that on earth.

thus
W on moon = 65 N / 6
W on moon = 10.8333333 N

Answer 3

Based from the facts on your question:
F = 65N
m (F/g) = 40.625 kg
F (moon) (6.77083333333.......)
6 times 'g' is 9.6 m/s^2

In case you are told to express your answer in significant figures, then, it would be:
mass on earth: 41kg
weight on moon: 6.8N

where:
F = force exerted by the earth on the meteorite
m = mass of the meteorite
g = acceleration due to gravity (1.6N/kg)

Hope it helps...
Just a question about your question....
The unit N (netwon) is for FORCE, and FORCE = mg. therefore, it is indeed questionable to put there 1.6N/kg, when you are finding the force. ??? :-)

Answer 4

Using F=ma; F=mg

If moon g=1.6 N/kg (Or m/s squared)

F=mg
65=m(1.6)

Therefore m=65/1.6=40.625Kg

g is an acceleration, F is the weight of this object and the mass is the ammount of matter of the object. On the moon it is less than the Earth, as g on earth is 9.81 m/s squared.

To find out the acceleration difference:

g(Earth)/g(moon)
1.6/9.81=6.13m/s Squared

therefore F(moon)=F(earth)/6.13

F(moon)= 65/6.13=10.6N.

Answer 5

gravity on the moon is 1/6 of earths. the mass would be the same. weight would be 1/6 of what it is on earth.

Answer 6

It depends what the meteorite is made from.
