A
mass is a measure of the amount of physical material an object is comprised of
2
Q
what is weight?
A
weight is a measure of the force from gravity acting on a mass
3
Q
what is the equation for weight?
A
weight = mass x gravitational field strength
W = mg
4
Q
what is the equation for mass?
A
mass = weight / gravitational field strength
m = W / g
5
Q
what is the equation for the gravitational field strength?
A
gravitational field strength = weight / mass
g = W / m
