How do we measure gravity?

How do we measure gravity?Thanks to Newton, gravity is a measurable force. Not coincidentally, the international standard unit of force is called a Newton (N). On Earth’s surface, roughly 0.98N equals the downward force of gravity on 100 grams of mass.

Likewise, one kilogram of mass exerts a downward force of 9.8N. To calculate the force of gravity, physicists use the formula f = ma (force = mass x acceleration).

Since the acceleration of gravity is 9.8m/s2 on Earth – ie little g – we can easily calculate the Newton force of any mass. The average person’s mass is 70 kilograms, which multiplied by 9.8 gives you 686N – the force by which gravity keeps us all securely grounded.

Why do things smell?

More importantly, though, why does the How It Works team always smell so great? Must be all that knowledge we’ve got stored up
