If an object has a mass of 20 kg on a planet with a force of gravity of 4 m/s2. What is the object's weight?

Question

**Remember** W=mg

a
5 N
b
200 N
c
80 N
d
0.2 N

Answer 1

W=mg

Where:
W = weight
m = mass
g = force of gravity

Given:
m = 20 kg (mass of the object)
g = 4 m/s^2 (force of gravity on the planet)

Thus,

W = mg
W = 20 kg x 4 m/s^2
W = 80 N

Therefore, the answer is option C, 80 N.
