You multiply the mass by the gravity. Normal Earth gravity is about 9.8 (in meters/second2, or the equivalent newton/kilogram).

What is the weight of a 40kg object?

The weight of a 40kg object on Earth would be approximately 392.4 Newtons. Weight is calculated by multiplying the mass of an object by the acceleration due to gravity (9.81 m/s^2).


If a woman has a mass of 50kg calculate her weight in newtons?

equation: weight= mass*gravity weight = 50kg * 9.8 m/s or 10 m/s (samething) =500 newtons or 490 newtons ~hope that helped!


What is the mass and weight of a 10-kg object on Earth?

10 kilograms is the mass. To calculate the weight (in newtons), multiply the mass by 9.8.


How do you calculate mass if you are only given weight in Newtons?

Weight = (mass) x (local acceleration of gravity). Mass = (weight) / (local acceleration of gravity) If you know the weight and the local acceleration of gravity, you can calculate the mass. Anywhere on or near the surface of the earth, the local acceleration of gravity is about 9.82 meters per second2 . As an example, an object with a weight of 9.82 newtons has a mass of one kilogram.


What is your weight and mass on earth if you way 40 kg?

40kg of mass, 400 (approx) N of weight.


What is the mass of a rock that weighs 59 newtons?

The mass of the rock is 6 kg. This is calculated by dividing the weight (in newtons) by the acceleration due to gravity (9.81 m/s^2). The formula to calculate mass is mass = weight / gravitational acceleration.


How much does 40 kg weigh on earth in newtons?

The 40kg student's force (weight) on Earth is about 392.28 newtons. (Force = mass x acceleration). Earth's acceleration is 9.807 meters per second squared.


What are weight and mass measured in?

Weight in Newtons Mass in kilograms


What is the weight of a 150lb person in newtons and what is the mass in kilograms?

Force or weight is approximately 667 newtons and mass is approximately 68kg


What is the weight of a 40 kg object?

The 40kg student's force (weight) on Earth is about 392.28 newtons. (Force = mass x acceleration). Earth's acceleration is 9.807 meters per second squared.


What is the weight in newtons for lily lightweight who has a mass of 40 kg?

What planet are you on? I don't mean to be a wise-ass, but weight depends upon the acceleration of gravity, which is different on different planets, whereas mass is the same no matter where you are. On the surface of the Earth, the acceleration due to gravity is 9.8 m/s2, so a 40-kg mass will weigh 40 x 9.8 = 392 newtons.


What is the weight in newtons of an object with the mass of 2000 grams?

To find the weight in newtons, you need to convert the mass from grams to kilograms first. Since 1 kg = 1000 g, the mass of 2000 grams is 2 kg. Next, you can calculate the weight using the formula weight = mass * acceleration due to gravity. Acceleration due to gravity is approximately 9.81 m/s^2. Thus, the weight of an object with a mass of 2000 grams is about 19.62 newtons.
