how much does a 110kg person weigh on earth

Answer 1

How much does a 110kg person weigh on earth. Please explain

**Answer:**

In science and engineering, the weight of an object is the force on the object due to gravity. This is often expressed in the formula

$$W = m g$$

where $W$ is the weight, $m$ the mass of the object, and $g$ gravitational acceleration.

(http://en.wikipedia.org/wiki/Weight)

At different points on Earth, gravitational acceleration is between 9.78 and $9.82 \, m/s^2$ depending on latitude, with a conventional standard value of exactly $9.80665 \, m/s^2$

(http://en.wikipedia.org/wiki/Gravitational_acceleration)

We are given:

$$m = 110 \, kg$$

Thus:

$$W = m * g = 110 * 9.80665 \approx 1078.7 \, kg * m/s^2 = \mathbf{1078.7} \, N$$

So, 110kg person weigh 1078.7 N on earth surface.
