We have all been there, weighed yourself first thing in the morning, exercised came back 20 minutes later and find out that you have gained 5 pounds. How is this possible?
In science and engineering, the weight of an object is the force on the object due to gravity pushing down on it. So if the gravitational field changes at all so can your weight. Does this mean you will weight different when its a full moon rather than a new moon? Maybe…
The arrows are gravity
Since the weights of different bodies at the same location are proportional to their masses, weight is often used as a measure of mass mass, in physics, the quantity of matter in a body regardless of its volume or of any forces acting on it. The term should not be confused with weight, which is the measure of the force of gravity acting on a body.
However, the two are not the same; mass is a measure of the amount of matter present in a body and thus has the same value at different locations, and weight varies depending upon the location of the body in the earth’s gravitational field (or the gravitational field of some other astronomical body).
Ok so before we go blaming the moon, there are some other factors to consider mostly bloating and excess weight. The best thing to do f your that concerned is take your weight 3 times a few minutes apart and average it out. Don’t weigh yourself everyday though you will just drive yourself crazy. I recommend Mondays as it can set the tone for the whole week.
