Is the weight-mass of a CD more or less than a kg?
The mass is less than 1 kg.
What is the weight of a cement block in Kilograms?
A larger block will weigh more, a smaller block will weigh less. Also, kilograms is a unit of mass, not of weight.
Does a pencil weigh less than a kilogram?
Please note that a kilogram is a unit of mass - NOT a unit of weight. And yes, a pencil has a mass that is considerably less than a kilogram. For comparison, a kilogram is the mass of a liter of water.
Why are mass and weight the same everywhere on earth?
They are not the same, because they are completely different concepts. They are more or less proportional - a mass of one kilogram will have a weight of approximately 9.8 Newton - because the gravity is more or less the same on different parts of the Earth: whether you are at the North Pole, or the Equator, the distance from the center of the Earth won't change much.
Are weight and mass he same thing?
No. The relationship is: weight = mass x gravity Mass causes both weight, and inertia. Weight is the force of attraction by gravity, and also depends on the gravitational field, not just on the mass. For more information, check the Wikipedia article "Mass versus weight".
Would mass be more or less on the moon?
Mass is the same no matter where you are. Weight is less, but mass is the same.
What measurement is used more often by scientists mass or weight?
they are the same thing.
Is the weight-mass of a CD more or less than a kg?
The mass is less than 1 kg.
If your mass in weighing machine is 42kg then your real mass will be less or more than 42kg?
the real weight will be more.because due to buoyancy our weight will be shown less on weighing machine.....
Between mass and weight the more fundamental quantity is?
Mass. Weight is different depending on gravity, but mass is always the same. On the Moon an astronaut weighs less, but has the same mass that they have on Earth.
What is the relationship weight v mass?
The relationship is: weight = mass x gravity On Earth, since gravity is about 9.8 meter/second2, or the equivalent 9.8 newton/kilogram, that means that a mass of 1 kilogram has a weight of 9.8 newton. In other places, with more or less gravity, the same mass will also weigh more, or less.
How does the the type of surface affect the weight of the shoe a distance of 1 meter long?
That is a big shoe! Less surface area, less mass. if there is deep traction in a shoe there is more surface area and more material. if there is a flat surface there is less surface area less material less mass less weight.
How does mass effect efficiency?
The mass affects the efficiency of an object. It adds more weight, which causes more friction. More friction=less efficiency
Is the mass of an object more on the moon?
No. The mass of an object does not change. However and object's weight, which is a function of mass and gravity, is less on the moon than on earth.
Would you weigh less or more in space?
You would weigh less, but your mass would stay the same. Weight is a result of gravity, mass is an inherent property of matter.
Why is mass more useful than weight for measured matter?
Scientists prefer to rely on mass instead of weight when measuring because weight will change depending on location, whereas mass remains constant regardless of location. You could weigh 60 pounds on earth, but 10 pounds on the moon, but your mass would be the same on earth and the moon.
When brought to the surface of a moon will a mass have more or less weight when it did on the surface of th earth?
The mass will definitely weigh less as the moon is less massive than the Earth and hence the Gravity of the Moon will be lesser than Earth. The object's weight will be 1/6 times that on Earth.
