Answer:
Explanation:
Given parameters:
Gravity on the moon = 1.62m/s²
Gravity on earth = 9.8m/s²
mass of cannon ball = 20kg
Unknown:
weight of cannonball = ?
Solution:
The weight of an object is the vertical force on a body as a result of a gravity:
W = m x g
where m is the mass
g is the acceleration due to gravity
mass is the same everywhere if the amount of matter does not change.
Weight on moon = m x g = 20 x 1.62 = 32.4N
Weight on earth = m x g = 20 x 9.8 = 196N
