From Newton’s laws, we have F = m*a. In the MKS system, F is in Newtons, m is the mass in kg., and a is acceleration in m/sec
2
. In MKS, the a for gravity is 9.8m/sec
2
and so the weight is 5*9.8 =
49 Newtons
.
What is the weight of a 5kg object on the surface of the earth?
So a 5kg object has a
mass of 5kg
. The weight you associate with it is only relevant on Earth (under its specific gravity) and in fact really the kilogram-force measurement which is measured in Newtons (5kg x 9.8m/s2 = 49.2N). … Commonly, it means the object weighs 5kg.
What is the weight of an object with a mass of 5kg?
So a
5kg
object has a mass of 5kg. The weight you associate with it is only relevant on Earth (under its specific gravity) and in fact really the kilogram-force measurement which is measured in Newtons (5kg x 9.8m/s2 = 49.2N). … Commonly, it means the object weighs 5kg.
What would be the weight of a 1 kg object?
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.
What is 5kg mass?
Answer: So a 5 kg object has a mass of 5 kg. The weight you associate with it is only relevant on Earth (under its specific gravity) and in fact really the kilogram-force measurement which is measured in Newtons (5 kg x 9.8 m/s 2 =
49.2 N
). Commonly, it means the object weighs 5 kg.
What is the weight of an object whose mass is 56 kg?
An object weighing
549 Newtons
on the surface of the earth will have a mass of about 56 kilograms. m = 56 kg.
How can I calculate weight?
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.
What is 50n in KG?

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 things weigh 2kg?

What object is 1kg?
A kilogram is about: the
mass of a liter bottle of water
. very close to 10% more than 2 pounds (within a quarter of a percent) very very close to 2.205 pounds (accurate to 3 decimal places)
What weighs more than 1kg?
Ans. Things which weigh more than 1 kg are
School bag, a brick and a big pumpkin
. Things which weigh less than 1 kg are Geometry box, slippers/shoes.
What is meant by 1 kg mass?
Kilogram (kg), basic unit of mass in the metric system. A kilogram is very nearly equal (it was originally intended to be exactly equal) to
the mass of 1,000 cubic cm of water
. The pound is defined as equal to 0.45359237 kg, exactly. … One joule is equal to one kilogram times metre squared per second squared.
What is SI unit of mass?
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 is weight class 9th?
The weight of a body is
the force with which it is attracted towards the centre of the earth
. The force of attraction of earth on a body is called as weight. … Weight is a vector quantity. Since the value of g changes from place to place,weight of a body also changes from place to place.
What is the weight of a 50 kg mass?
On earth your mass is 50kg and your weight (the force you exert on the ground) is
490 Newtons
.
