Question

Jamie has a mass of 35kg what is her weight on earth in newtons

Answer 1

Gravity on Earth = 10N/Kg
10N/Kg * 35Kg =350N

Answer 2

On eart 1 kg is equal to 9.8 N/kg
So you just have to do 35•9,8= 343N
343 N is the answer.
And it is NOT 343 N/kg because the kilograms of 35 and the kilograms of 9,8 simplify (they cancel each other) so the remaining unit of measure is newton
