Measure of the force of gravity that is expresed in newtons?

Answer 1

A force caused by gravity is known as a "gravitational force".

It can be measured in any convenient unit of force.

Many people call it "weight" and describe it in pounds or ounces.

Answer 2

Remember that Force = Mass times Acceleration, and that a Newton also equals mass X acceleration.

So you have to multiply g, which = 9.8 m/s2 by some mass to get a unit of Newton.

Example.

A 10 Kg ball falls towards earth. F = ma = 10 kg * -9.8 m/s2 = -98 Kg m / s2 = -98 Newtons.

So 1 Kg m / s2 = 1 Newton.

Answer 3

Gravity, being a force, is expressed in Newtons.

The general force of gravity can be described with the following equation:

Fg= (Gm1m2) / (r2)

where G is the gravitational constant (6.67 x 10-11 Nm2 / kg2), m1 and m2 are masses of the objects that are attracted to one another, and r is the radius or distance between them.

On a planet with a known acceleration due to gravity, the equation can be simplified. Newton's 2nd Law equation:

Fg=ma

where m is the mass of an object in the gravitational field, and a is the acceleration of gravity.

To find of the force of gravity on an object (also known as weight), you need to know its mass and the acceleration. The acceleration due to gravity on earth is 9.8 m/s2. The force of gravity then depends on the mass.

Example:

How much does a 10 kg object weigh on earth?

F= ma
F= (10kg)(9.8m/s2)
F= 98 (kg)(m/s2) or 98 Newtons.

Answer 4

"Newtons" is not a unit of gravity.

The acceleration of gravity on or near the surface of the Earth is about

9.8 meters/second2 .So the gravitational forces between the Earth and any other mass are 9.8 newtonsfor each kilogram of mass in the other mass. One of these forces is typically

called "weight". The other one is equal, acts in the opposite direction, and is

typically ignored.

This number is different in other places.

Answer 5

The measure of the force of gravity is the weight of an object, which is typically expressed in newtons. Weight is the force exerted on an object due to gravity, and it is defined as mass multiplied by the acceleration due to gravity (9.8 m/s^2 on Earth).

Answer 6

Since force is measured in Newtons... it is (about) the same force as the weight of 102g on Earth. The force of a newton is relative to the metre per second per second it is moving through

Answer 7

On or near the surface of the Earth, it's 9.8 newtons per kilogram of mass.
