# How do you calculate body weight in physics?

## How do you calculate body weight in physics?

The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.

How do you calculate ideal body weight?

Ideal body weight is computed in men as 50 + (0.91 × [height in centimeters − 152.4]) and in women as 45.5 + (0.91 × [height in centimeters − 152.4]). A simple alternative would be to compute ideal body weight as the weight corresponding to an ideal body mass index of 22 kg/m2.

### What is the equation of weight?

Weight can be calculated using the equation: weight = mass × gravitational field strength. W = m g. This is when: weight (W) is measured in newtons (N)

What is weight measured in physics?

Weight is a measure ofthe force of gravity on a physical object and is measured in newtons.

## What should be my weight if my height is 5 feet?

Weight and height guide chart

Height Weight
5ft (60″) 97 to 123 lbs. 128 to 148 lbs.
5ft 1″ (61″) 100 to 127 lbs. 132 to 153 lbs.
5ft 2″ (62″) 104 to 131 lbs. 136 to 158 lbs.
5ft 3″ (63″) 107 to 135 lbs. 141 to 163 lbs.

What is correct weight and height for age in KG?

Adults Weight to Height Ratio Chart
Height Female Male
5′ 0″ (152 cm) 90/110 lb (40.8/49.9 kg) 95/117 lb (43.1/53 kg)
5′ 1″ (155 cm) 95/116 lb (43.1/52.6 kg) 101/123 lb (45.8/55.8 kg)
5′ 2″ (157 cm) 99/121 lb (44.9/54.9 kg) 106/130 lb (48.1/58.9 kg)

### What is the equation for work done?

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work.

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 SI unit of weight?

The SI unit of mass is the kilogram (kg). Thus, the SI unit of the quantity weight defined in this way (force) is the newton (N).

What should a 5 7 female weigh in kg?

Adults Weight to Height Ratio Chart
Height Female Male
5′ 6″ (168 cm) 117/143 lb (53/64.8 kg) 128/156 lb (58/70.7 kg)
5′ 7″ (170 cm) 122/149 lb (55.3/67.6 kg) 133/163 lb (60.3/73.9 kg)
5′ 8″ (173 cm) 126/154 lb (57.1/69.8 kg) 139/169 lb (63/76.6 kg)

### How do you calculate your ideal body weight?

Calculating Ideal Body Weight. Women should weigh a bit less, so the ideal body weight calculation starts with 100 pounds for the first 5 feet of height, and you only add 5 pounds for each additional inch. If you’re under 5 feet tall, subtract 2 pounds for each inch under 5 feet.

Which is the correct formula for the weight equation?

The weight formula can be explained as follows: Weight = mass × gravity The formula for this is:

## How to calculate IBW based on height and weight?

Male: 50.0 kg + 2.3 kg per inch over 5 feet. Female: 45.5 kg + 2.3 kg per inch over 5 feet. Similar to the Hamwi Formula, it was originally intended as a basis for medicinal dosages based on weight and height. Over time, the formula became a universal determinant of IBW.

Who is the author of the ideal body weight equation?

He is the author of “The Origin of the ‘Ideal’ Body Weight Equations”, a comprehensive literature review on the creation of and iterations to the ideal body weight formula over time. Dr. Pai conducts research on the optimization of antimicrobial drug dosing, most recently in the obese population. Are you Dr. Manjunath Pai?
