Question

7 Calculate the weight of an apple of mass 100 grams

Answer 1

Answer:

See the anwers below

Explanation:

To solve this problem we must understand that the weight of any$W = 0.1*10\\W = 1 [N]$body is defined as the product of mass by gravitational acceleration. Gravitational acceleration depends on the place in space where a certain body is located.

$W = m*g$

where:

W = weight [N]

m = mass = 100 [g] = 0.1 [kg]

g = gravity acceleration [m/s²] or [N/kg]

Now for the Earth

$W =m*g\\W =0.1*10\\W = 1[N]$

For the Moon

$W = m*g\\W =0.1*1.6\\W = 0.16 [N]$
