Hi,
I weight 55kg at sea level.
I know gravity pulls on a 1kg mass with a force of 9.8 Newtons.
But I can't figure out how to work out my mass?
As a side issue. If some was to shove me sideways. would the force (impulse) they have to exert be proportional to my weight. I know inertia is proportional to mass. Would the resultant force be the product (parallelogram) of the sideways shove and downward force of gravity?
I hope that makes sense :-)

your Mass is 55kg as Mass is measured in kg, if your trying to find your weight then thats your
mass X gravitational field strength which is 9.81 so your weight would be 55X9.81=539.55.
gravity does change for when your on the moon, and then the new gravitational field strength is 1.96 so your mass stays the same but your weight changes because weight = Mass X g(gravitational field strength) .So your new weight is 1.6X55=88
and for mass = density x volume
and thats another equation because density of a human is nearly 1
if someone was to shove you sideways yes they would have to apply the sideways force and there will be a force of gravity acting down on you.
The resultant of the two wont be the product of the two but will be resolving the two forces.

Isn't Mass something like Volume x Specific Gravity?
If so, you'll have to dunk yourself in a tank of water to find yr volume and x it by the SG of a human body, which must be about 1.
There's some rubbish answers on here. If 55kg is your weight ( on a weighing machine) that is NOT your mass. Your mass does not change ; your weight can. On the moon, yr weight would be just over 9kg, but your mass would be the same as on earth.

As earlier stated your mass is 55kg
Your weight is measured in newtons. 1kg = 9.81N therefore your weight is 9.81*55=
As to the impulse question yes the resultant force on both you and the other person would be due to the shove and gravity!

Do what Archimedes did and jump in the bath. Eureka! Actually you need a vessel with straight sides so that you can measure the displacement accurately.

Kilogram is a measurement of mass. Your mass is 55kg.

your mass is 55kg
your weight is 55 x 9.8
your weight is 55 x 9.8
