Question

The weight of an object is the force generated by Earth's gravity accelerating the object's ______.

Answer 1

Answer: Speed

Step-by-step explanation:

Answer 2

Answer:

mass

Step-by-step explanation:

From the universal law of gravity

$F=G\frac{Mm}{r^2}$

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

$\\\Rightarrow ma=G\frac{Mm}{r^2}\\\Rightarrow a=G\frac{M}{r^2}\\\Rightarrow a=6.674\times 10^{-11}\frac{5.972\times 10^{24}}{(6.371\times 10^6)^2}\\\Rightarrow a=9.81\ m/s^2$

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
