Well, darling, the mass of the book is 1kg, that's a fact. Now, when it comes to weight on Earth, it would be approximately 9.8 Newtons, because weight takes into account the force of gravity acting on the mass. Hope that clears things up for you, sweetie.
9.8 newtons (2.205 pounds) (both rounded)
Both 1kg of iron and 1kg of cotton would have the same weight in a vacuum. Weight is determined by mass, which is the same for both objects in this scenario.
No, both 1kg of lead and 1kg of feather would weigh the same in a vacuum because weight depends on mass, and both objects have a mass of 1kg. Gravity affects weight, but in a vacuum, there is no air to provide resistance, so both objects would fall at the same rate.
'Kg' is a unit of mass, not weight. On Earth, 1 kg of mass weighs 9.8 newtons, and 1 newton is the weight of about 0.102 kg of mass. On the moon, the same kg of mass weighs 1.6 newtons, and 1 newton is the weight of about 0.616 kg of mass. On Mars, the same kg of mass weighs 3.7 newtons, and 1 newton is the weight of about 0.269 kg of mass.
The weight of 1 kg of mass is about 9.8 Newtons on the surface of the Earth. This is because weight is the force exerted by gravity on an object of mass, and on Earth, gravity accelerates objects at approximately 9.8 m/s^2.
The weight of an object on Earth is the same as its mass, which is 1kg in this case. Weight is a measure of the force of gravity acting on an object's mass.
9.8 newtons (2.205 pounds) (both rounded)
The weight of any object is caused by the gravitational field of the nearest, large object. For a 1kg mass on the Earth its weight is about 10 Newtons. On the moon, the same 1kg mass would have a weight of about 2 Newtons.
The weight of 1 kg is 1 kg on Earth. If the force is to be determined, it is 9.8 Newtons due to gravity.
Approximately 9.8 Newtons (Force weight = mass * acceleration of gravity)
the Weight of an object is the force gravity exerts on it. So if you take a 1kg mass, on earth it pushes down 9.8n. but on say, the moon, you could take a 2kg mass, the amount of force it exerts downwards (the weight) would be less then the 1kg does on earth. So yes, but not if they are in the same place!
Both 1kg of iron and 1kg of cotton would have the same weight in a vacuum. Weight is determined by mass, which is the same for both objects in this scenario.
The mass is twice as much, so multiply by 2. The radius is 3 times as much--the gravitational force is inversely proportional to the square of the radius, so multiply by 1/9.2 X 1kg/9 = 0.2 kg.
The weight of an object is its mass times the acceleration of gravity. The acceleration of gravity at the center of the Earth is zero. A 1 kg mass at the center of the Earth still has a mass of 1 kg, but the force of attraction between the 1kg mass and all the other mass around it will add up to zero.
No, both 1kg of lead and 1kg of feather would weigh the same in a vacuum because weight depends on mass, and both objects have a mass of 1kg. Gravity affects weight, but in a vacuum, there is no air to provide resistance, so both objects would fall at the same rate.
The force with which Earth attracts a body of mass 1kg on its surface is approximately 9.81 Newtons.
