W = mg, where W is weight in Newtons, m is mass in kg and g is acceleration due to gravity, 9.8m/s2.

W = 5kg x 9.8m/s2 = 49N = 50N rounded to 1 significant figure

What is the mass of a book that weighs 5 Newtons on earth?

The Earth weight of a particular substance in newtons is the product of its mass (in kg) and 9.8 meters per second per second, following this conclusion we shall get the mass of a substance if we divide its weight by 9.8 . Therefore applying this theory the mass of the book must or would be 0.51 kg.

What is the formula for calculating the force in newtons when a mass of 5 kg is accelerated at a rate of 2 m/sec2?

The formula for calculating force (F) in newtons is F mass (m) x acceleration (a). In this case, with a mass of 5 kg and acceleration of 2 m/sec2, the force can be calculated as F 5 kg x 2 m/sec2 10 newtons.


What is the mass of an object if it weighs 5 newtons?

The mass of an object can be determined using the formula: mass = weight ÷ gravitational acceleration. Assuming the gravitational acceleration is 9.81 m/s^2, the mass of an object that weighs 5 newtons would be approximately 0.51 kg (5 ÷ 9.81 ≈ 0.51).


How many newtons are on a scale of 5 newtons?

the two quantities are different - 5kg indicates the mass of the object, ie how much stuff it contains, a newton is a force, in this case a weight (a force produced by gravity, the mutual attraction of two objects with mass). The weight produced by 5kg depends on g, which is a function of how massive the other object is and how far away you are from its center. Assuming you mean 'how many newtons is 5kg on the surface of earth', g is about 9.81. To get the weight (in newtons) from the mass (in kg) all you do is multiply by g - so 5kg by 9.81 roughly equals 49 newtons. The apparent weight may be less than this. If you only want a rough estimate, then if we approximate the g from 9.81 to 10, then the force (in Newtons) is almost equal to the mass (in kg) multiplied by 10. Therefore 5kg is almost 50N (but actually less than 50). It is not accurate but it gives you an idea of the magnitude.


What is the mass if a rock that weighs 49 newtons?

The rock's mass on earth will be 5kg (mass = force in newtons / 9.807)


How do you convert kilograms to newtons?

Kilograms to Newtons, just multiply the Mass in kilograms by 9.81 and you will have your Newtons True on the surface of the earth, but nowhere else. These things are different, like a cat is not like a drop of water, So they are not inter-convertible. The gravitational force (in Newtons) on a mass (in kg) is its mass multiplied by the local value of the acceleration due to gravity.
