Question

If a rock has a mass of 45kg, what is:
a. its weight on Earth : _______________
b. its mass on the moon: ________________
c. its weight on the moon: ______________

Please do include the calculation, thank you!

Answer 1

Answer:

a) W = m x g

W = 45 x 9.8 = 441N

b) 45 kg

Mass of an object remains same everywhere. It is the value of 'g' that differs.

c) $weight \: on \: moon = \frac{weight \: on \: earth}{6}$

Weight on moon = 441/6 = 73.5 N
