When the newspaper mentioned 300kg, it actually meant 300N
tecnically...
Let's say you weigh 60kg... Actually you're wrong to say that your
weight is 60kg... It is actually 60N because what you see on the
weighing scale is subjected to Earth's gravity pull of 9.81
m/s^2.... However, we stick to calling it 60kg because we're all
used to it... It has become a habit already... and now it has
become a confusion for many people...
So remember...
F = ma (or W = mg)
where F = force in Newtons, m = mass in kg, a = acceleration
( W = weight in Newtons, m = mass in kg, g = Earth's gravitational
pull = 9.81 m/s^2 )
