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/s^{2} on Earth. The formula for calculating weight is F = m × 9.8 m/s^{2}, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
Also, What is formula of weight calculation?
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/s^{2}. It is also known as the gravitational constant.
Hereof, What is my ideal weight in kg?
Updated Equations for Ideal Weight
- Weight in pounds = 5 x BMI + (BMI divided by 5) x (Height in inches minus 60)
- Weight in kilograms = 2.2 x BMI + (3.5 x BMI) x (Height in meters minus 1.5)
Also to know What is the formula to calculate work done? Mathematically, the concept of work done W equals the force f times the distance (d), that is W = f. d and if the force is exerted at an angle θ to the displacement, then work done is calculated as W = f . d cos θ.
What is the normal weight for 25 year old woman?
American women aged 20 years and above weigh an average of 170.6 pounds (lbs), according to the Centers for Disease Control and Prevention (CDC) . Height-wise, the average adult female is 5 feet 3.7 inches, and her waist measures 38.2 inches. While these numbers may be the average, they are not a measure of health.

What is gravity’s formula?
It is usually written like this (G is the gravitational constant): F = Gm_{1}m_{2}/r^{2}. Another, common, gravity formula is the one you learned in school: the acceleration due to the gravity of the Earth, on a test mass.
What is Newton formula?
Force (Newton) = Mass of body × Acceleration. Or, F = [M^{1} L^{0} T^{0}] × [M^{0} L^{1} T^{–}^{2}] = M^{1} L^{1} T^{–}^{2}.
What is area formula?
Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s^{2} (square).

How can I lose 10 kgs in a month?
To lose 10 kgs, we must note that we should burn extra calories to create a calorie deficit. With a balanced diet behaviour, include 30 minutes of physical exercises in your daily routine. You can also opt for Yoga which gives fantastic results if practised at the start of the day.
What is current formula?
The relationship between current and resistance in an electric circuit. Current is usually denoted by the symbol I. Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is I = V/R.
How do you calculate positive work?
1 J = 1 N m. Work can be either positive or negative: if the force has a component in the same direction as the displacement of the object, the force is doing positive work. If the force has a component in the direction opposite to the displacement, the force does negative work.
What is the formula of time and work?
Important Time and Work Formula
Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work. If a piece of work is done in x number of days, then the work done in one day = 1/x.
What is the perfect weight for a woman?
For example, if a woman is 5’4” and weighs 320 pounds, her “ideal weight” could be between 108-132 pounds. She is approximately 200 pounds above her ideal weight and could lose 100 pounds or more with weight loss surgery.
What is a normal weight for a woman?
How much does the average American woman weigh? The average American woman 20 years old and up weighs 170.6 pounds and stands at 63.7 inches (almost 5 feet, 4 inches) tall.
What is the normal weight of a woman in KG?
As per the CDC report, the average weight of American women in 2015-2016 was 77.4 kg (170.6 lb) in 2015–2016, up from 74.3 kg (163.8 lb) in 1999–2000. To find out if any person is underweight, normal-weight, overweight, or obese, their Body Mass Index (BMI) is calculated from weight and height.
Why is gravity 9.81 ms 2?
In SI units, G has the value 6.67 × 10^{–}^{11} Newtons kg^{–}^{2} m^{2}. The acceleration g=F/m_{1} 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 s^{–}^{2}. …
How do you calculate work?
The formula for work is , work equals force times distance. In this case, there is only one force acting upon the object: the force due to gravity. Plug in our given information for the distance to solve for the work done by gravity. Remember, since the object will be moving downward, the distance should be negative.
What is gravity and how is it calculated?
On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earth’s surface the acceleration of gravity is about 9.8 metres (32 feet) 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.

Does Newton’s first law have a formula?
Newton’s first law says that if the net force on an object is zero ( Σ F = 0 Sigma F=0 ΣF=0Sigma, F, equals, 0), then that object will have zero acceleration. … In other words, constant zero velocity—at rest—or constant non-zero velocity—moving with a constant velocity.
How do we calculate area?
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
