What is the surface gravity on earth in newtons?

Answer 1

in SI units is measured in m/s² (metres per second per second, equivalently written

as m·s−2 or N/kg). It has an approximate value of 9.8 m/s², which means that,

ignoring air resistance, the speed of an object falling freely near the Earth's surface

increases by about 9.8 metres per second every second. This quantity is informally

known as "little g" (contrasted with G, the gravitational constant, known as "big G")

Another way to describe it:

9.81 newtons (2.205 pounds) of force for each kilogram of mass.

Answer 2

9.8 m/s2

You can generalize and say that the surface acceleration due to gravity of the Earth is 9.8 meters per second per second.

However, you will find that this exact value is different on different surface locations of the Earth. This is due to the fact that the Earth is not entirely spherical. The official term for it is an "oblate spheroid."

Answer 3

'Newtons' is not an appropriate unit for the measurement of gravity.

The newton is a unit of force. We know positively that the gravitational force on different
objects at the surface of the earth is not constant ... observe that your weight is not the
same as my weight.

The gravitational force between the earth and an object depends on the object's mass.
The force on more massive objects is greater, i.e. they weigh more.

What is constant at the surface of the earth is the acceleration of gravity. That's roughly
9.8 meters (32.2 ft) per second2.

Answer 4

The surface gravity on Earth is approximately 9.81 newtons per kilogram. This means that a 1 kg mass on Earth's surface experiences a force of 9.81 newtons due to gravity.
