The general formula to find the weight is given as, W = mg (N/kg). Here ‘g’ represents the acceleration due to gravity. On the earth, the value of g is 9.8 m/s2. It is also known as the gravitational constant.

Also, What is the weight formula?

Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.

Hereof, What is gravity’s formula?

It is usually written like this (G is the gravitational constant): F = Gm1m2/r2. Another, common, gravity formula is the one you learned in school: the acceleration due to the gravity of the Earth, on a test mass.

Also to know What is Newton formula? Force (Newton) = Mass of body × Acceleration. Or, F = [M1 L0 T0] × [M0 L1 T2] = M1 L1 T2.

What is my weight for my age?

Three simplified linear equations were derived to calculate mean weight for age. For Infants < 12 months: Weight (kg) = (age in months + 9)/2 For Children aged 1-5 years: Weight (kg) = 2 x (age in years + 5) For Children aged 5-14 years: Weight (kg) = 4 x age in years.

## Why is gravity 9.81 ms 2?

In SI units, G has the value 6.67 × 1011 Newtons kg2 m2. The acceleration g=F/m1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s2. …

## What is value of g?

Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location.

## Why is g GM r2?

From this is it straightforward to derive another, common, gravity equation, that which gives the acceleration due to gravity, g, here on the surface of the Earth: g = GM/r2, … G (without the subscripts) is the gravitational constant, and c is the speed of light.

## What is SI unit of Newton?

Newton, absolute unit of force in the International System of Units (SI units), abbreviated N. It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second.

## What is Newton’s third law example?

Examples of Newton’s third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton’s third law when designing rockets and other projectile devices.

## What are the 5 equations of motion?

In circumstances of constant acceleration, these simpler equations of motion are usually referred to as the “SUVAT” equations, arising from the definitions of kinematic quantities: displacement (S), initial velocity (u), final velocity (v), acceleration (a), and time (t).

## Where is gravity the strongest?

Earth’s Gravity is strongest on the ground, usually at sea level, and weaker as you move away from the core, eg the peak of Mt. Everest. The gravity at the poles is stronger than the equator, partly because the obloid earth is slightly wider, but only by a small ratio.

## What does 9.8 m s mean?

A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). This numerical value for the acceleration of a free-falling object is such an important value that it is given a special name. … The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.

## At what height gravity is zero?

Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m·s2 per 3,200 km.)

## What is G called?

G is called Universal Gravitation Constant because its value i.e. 6.67 x 1011 Nm2kg2 is constant thought the universe.

## What is small G in physics?

The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G (capital G).

## Is value of G actually constant?

In every place of both Earth and the universe, the value of G remains constant. The value of G does not change with a change in the height, and depth from the earth’s surface.

## What do G M and R stand for?

Weight of an object on Earth = Gravitational force exerted on an object by the Earth. … G=Gravitational constant, M=Mass of the Earth, and R=radius of the Earth.

## What is G in FG Gm1m2 r2?

• Newton’s Law of Gravita- tion states that two objects with masses m1 and m2, with a distance r between their cen- ters, attract each other with a force F given by: F = Gm1m2/r2 where G is the Universal Grav- itational Constant (equal to: 6.672 x 10-11Nm2/kg2).
