How does a weighing machine display the mass of the body?
A weighing machines displays the mass of the body by measuring the weight of the body. Weight is the force exerted by the body due to gravity that is weight is mass*gravitational acceleration. Most weighing machines are designed to measure this force exerted on them.
Does a weighing scale measure normal force or mass?
Since you stand on a weighing scale machine, it measure the normal force. The force of gravity on your body that pushes you down onto the scales and the scales measure this force pushing down on them. If you're taking measurements with a device based on a balance, you're measuring mass. Click to see full answer.
What is the difference between a balance and weighing machine?
A balance also measures force but it measures the force on one object by comparing it to the force exerted on another. If you go up a hill, the force will decrease but on both sides so the comparison of force in N to mass on If a “weighing machine" uses a spring, load cell or similar, it will measure the force that gravity exerts on the object.
Can a weighing machine measure force of attraction?
Technically speaking, weighing machines should measure your weight, which is the force of attraction due to gravity between you and the Earth. In common everyday usage Kg is used as a measure of weight. However, if you use the formal SI definition as used by physicists, then Kg is a unit of mass, not of weight (force).
Does weighing machine show mass or weight?
The weighing machine measures weight of the body or mass of the body.
How does a weighing machine measure mass?
It measures the normal reaction of the body. When a body is put over the machine body is pulled towards the center of the earth. As the body is pulled towards the earth it applies force on the machine and the machine is calibrated in such way that it gives the mass of the body.
Does mass and weight the same?
Mass is a fundamental measurement of how much matter an object contains. Weight is a measurement of the gravitational force on an object. It not only depends on the object's mass, but also on its location. Therefore, weight is actually a measure of force.
Which instrument measures mass?
balanceFor the majority of everyday objects, a balance is used to determine an object's mass. The balance compares an object with a known mass to the object in question. Different types of balances include digital scientific balances and beam balances, such as a triple beam balance.
How is mass measured?
The same source goes on to state: “Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. Weight is measured on a scale. The Mass of an object doesn't change when an object's location changes. Weight, on the other hand does change with location.”.
What does weight mean in physics?
I did that because in the world of commerce, trade, and law, weight always means amount of matter (which your physics teacher calls mass)—in other words the word weight, contrary to your physics teacher and textbook, sometimes means something other than a force, because sometimes it means a mass.
How to find mass on the moon?
On the Moon or anywhere else the weight (force) will be measured in newtons (apples) and then divided by gravitational acceleration to determine mass in kilograms. On the moon the mass of a 1600 newton astronaut is found by dividing by 1.6, which is close to the metric acceleration of gravity on the Moon’s surface.
What is the deflection of a weighing scale?
The weighing scale consists of a spring inside it. The deflection of the spring due to loading is proportional to the force acting (weight) on it which in turn is proportional to the mass of the person. In case of non-accelerating frame of reference, weight equals normal reaction.
What would happen if a man took 100 kg of mass to the moon?
If however, instead of a scale, he took a balance and 100 kg mass to the moon, he would be able to measure his actual mass, because the scale would stay in balance regardless of how much, or how little, the gravitational pull was. He would discover that his mass had remained unchanged.
Can weight be measured in kg?
But as we know that weight cannot be measured in kg because it is the unit of mass, so in actual science it is given by kgf. So the weighing scales gives us the weight in kgf. It can be converted to force in newton by. 1kgf=9.81 newton. On the other hand answer to yours question is you must multiply your'.
Is weight a force?
In this context “weight” is a synonym for “mass” not for a particular type of force. The choice is not mass versus weight—it is mass versus force. The word weight is ambiguous, thanks to the physicists starting just after 1700, and can mean either mass or force.
Is your weight more than your mass?
Your weight on Earth is about 10 times more than your mass and a negative number! The Weighing Scale Does Not Actually Show Your Weight but, Your Mass! To understand this better, we need to understand vectors and scalars. Let’s understand the difference between scalar and vector quantities, applied in Kinematics.
Is mass a vector or a scalar?
So, that’s how we distinguish between scalars and vectors. Now, back to Weight and Mass. Mass is the amount of substance in your body. Do you think you can have negative substance in you body? No, and so, mass is a scalar quantity, just like how the scale on the measuring scale does not go below zero.
How do mechanical scales measure force?
And springs are used to measure force. The way they measure force is through the fact that if you shorten the length of a spring, a force is required. The greater the amount you shorten the spring, the more the force that is required.
What does Mac measure on a scale?
Professor Mac steps on scales to measure his weight. What do scales measure? The obvious answer is kilograms (or grams). That is what the reading on the scale indicates. However this is not what the scale is measuring. It actually measures force, and it is all to do with the way in which the scale is constructed.
Does a spring scale measure mass?
This simple experiment is an easy demonstration that a spring scale actually measures force and not mass.
Does a scale show weight in Newtons?
So your scale should display your weight in newtons. However it will normally indicate your weight in kilograms. But kilograms is actually a measure of your mass and this is where the confusion starts. Professor Mac stands on scales measuring his weight in newtons.
