Introduced to this in Physics
To get weight you multiply mass by 9.8 (gravity of the earth)
W = Mass x gravity
Since earth has a very large mass it exerts a very large force of attraction
Weight vs Mass
Apple, golf ball, and battery all have a mass of 100 grams
Force of gravity acting on them is 1 Neuton (pulled down by the force of 1 Newton)
Use Newton’s Spring Scale to measure the force
Number of newtons = 1/10th of a kilogram
Mass stays the same wherever you go
Gravity changes on the moon that’s why your weight changes
