In science and engineering, the weight of an object is the force acting on the object due to gravity . Some standard textbooks define weight as a vector quantity, the gravitational force acting on the object.
What defines the weight of an object?
Weight is a force acting on that matter . Mass resists any change in the motion of objects. In physics, the term weight has a specific meaning – which is the force that acts on a mass due to gravity . Weight is measured in newtons. Mass is measured in kilograms.
Why the weight of an object varies from one planet to another?
An object’s weight is dependent on its mass and how strongly gravity pulls on it . The strength of gravity depends on how far away one object is from another. That’s why the same object weighs different amounts on different planets. ... Your weight is different on other planets due to gravity.
How can I calculate weight?
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. The Newton is the SI unit for weight, and 1 Newton equals 0.225 pounds.
What is the weight of 1 kg of mass?
On Earth, a 1 kg object weighs 9.8 N , so to find the weight of an object in N simply multiply the mass by 9.8 N. Or, to find the mass in kg, divide the weight by 9.8 N.
Is mass equal to weight?
Your mass is the same no matter where you go in the universe ; your weight, on the other hand, changes from place to place. Mass is measured in kilograms; even though we usually talk about weight in kilograms, strictly speaking it should be measured in newtons, the units of force.
What is the weight of 1 kg mass object on the Earth?
Since g=9.80m/s2 g = 9.80 m/s 2 on Earth, the weight of a 1.00-kg object on Earth is 9.80 N : w=mg=(1.00kg)(9.80m/s2)=9.80N. w = m g = ( 1.00 kg ) ( 9.80 m/s 2 ) = 9.80 N . When the net external force on an object is its weight, we say that it is in free fall, that is, the only force acting on the object is gravity.
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.
What is the formula of weight?
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.
What is my ideal weight in kg?
- 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)
How much is 1 kg to calories?
| Kilograms Calories | 0.7 kg 5,401 kcal | 0.8 kg 6,173 kcal | 0.9 kg 6,945 kcal | 1 kg 7,716 kcal |

What is the weight of a 40 kg object?
Hence, the weight of the 40 kg mass is 392 ...
How do you convert kg to mass?
Divide the weight in Newtons by the acceleration of gravity to determine the mass of an object measured in Kilograms. On Earth, gravity accelerates at 9.8 meters per second squared (9.8 m/s 2 ).
Why is weight in kg?
Since there is no practical easy way to measure mass, in everyday life we use the kilogram as a unit of weight assuming that the gravitational field is fairly constant around earth . However scales have to be calibrated locally to compensate the slight gravitational field variation in different places.
What is more likely an object with 0 or 0 weight?
It is more likely for an object to have a weight of zero because the weight is the measure of the gravitational force on an object. It is possible to weigh nearly 0 in outer space. Matter, however, is the measure of matter in an object.
