what is mass
the quantity of matter within a given object
what is the symbol of mass
M
what is mass measured in
grams (g) and kilograms (kg).
does mass change in a chemical reaction
no mass is neither created nor destroyed in chemical reactions.
what is the difference between mass and weight
Mass is a fundamental measurement of how much matter an object contains. Weight is a measurement of the gravitational force on an object.
what are forces measured in
neutons (n)
what do forces change
speed shape and direction
what is the gravitational field strenght measured in
newtons per kg (n/kg)
does gravitations feild strenght change depending on location
yes Places with more mass, such as mountains, have stronger gravitational forces. Places with less mass underground, such as valleys and deep ocean trenches, have weaker gravitational forces.
how much does 1kg of mass weight in newtons
10 n
what is the equation to find weight
mass x gravitational field strenght
