Answer:
mass
Step-by-step explanation:
From the universal law of gravity
[tex]F=G\frac{Mm}{r^2}[/tex]
Where
G = Gravitational constant = 6.674×10⁻¹¹ m³/kg⋅s²
M = Mass of Earth = 5.972×10²⁴ kg
r = Radius of Earth = 6.371×10⁶ m
[tex]\\\Rightarrow ma=G\frac{Mm}{r^2}\\\Rightarrow a=G\frac{M}{r^2}\\\Rightarrow a=6.674\times 10^{-11}\frac{5.972\times 10^{24}}{(6.371\times 10^6)^2}\\\Rightarrow a=9.81\ m/s^2[/tex]
So the force of gravity acting on the mass of an object is
W = m×9.81
∴ Weight of an object is the product of mass and acceleration due to gravity
