How To Find Your Weight Without Scale

Download Article

Take you lot ever had questions about mass or how to detect the weight of the object itself? Well, scroll down to Footstep 1 to find the weight of an object without using a scale to weigh the object.

1

Figure out the volume of the object. Permit's say y'all accept a cube with a dimension of 10x10x10. The volume would be m.^[1]
2

Utilize the formula mass equals density times volume. This requires you to know the density of the object. If the object is water, for example, you know information technology has a density of 1 gram (0.035 oz) per cubic centimetres. So for a volume of water of 1000 cc, the weight is yard grams.^[ii]

Know the density of dissimilar matters: ^[3]
- Gold - 19.32
- Atomic number 82 - 11.3437
- Argent - 10.5020
- Copper - 8.5 to 8.eight
- Steel - 7.ix
- Iron - 7.four to 7.7
- Aluminium - ii.7
- Limestone two.6 to ii.8
- Glass - ii.4 to 2.eight
- Brick - i.four to 2.2
- Concrete - 2.2 to 2.5
- Water ice - 0.9
- Wax - 0.9
- Pinewood - 0.5
- Mercury - 13.543
- Seawater - 1.03
- Water - 1.0
- Petrol - 0.85

Note that this method is only used by astronauts to measure a spaceship. This won't piece of work in daily life, because resistance is everywhere.

Figure out the object'southward acceleration.
2
Figure out the mass through the force exerted. Exercise this by dividing the acceleration by the force exerted (past Newton's second police: force equals mass times acceleration).^[iv]
- For example, if a cube has an acceleration of 1000 millimetres per second squared (always mensurate in millimetres) and the force exerted is ii kilograms millimetres per second squared, then the cube must counterbalance 2 grams.

1

Balance a residue with lightweight, identical cups at both ends. This can be a ruler balanced on an object, or a string over something with little friction with cups tied at both ends.
2

Place the object at 1 cease, and fill the other cup with pure h2o until it balances with the object. If the object is also light to find the weight this way, you'll need to either decrease the friction at the caster or at the fulcrum, or use lighter-weight materials for the balance and cups.
3

Measure out the volume of the matching water, and convert to milliliters. The book in milliliters is the aforementioned every bit the weight in grams.^[5]

Question

Why is it recommended to use millimeters when a meter is an SI basic unit? Wouldn't it be easier? Unit-conversion wise, to measure in mm but catechumen it into m before calculating?

You cannot find weight with length measurements on their own. You demand other information such as weight for a specific cubic capacity.
Question

What is the mass of a ii centimeter wide rubber ball?

It depends upon the density of the prophylactic; it volition vary depending on how many air bubbles were inside the rubber when it was produced.
Question

I need to work out the weight of a large emphasis table merely I don't take a big enough scale. Is it possible to use the dimensions to determine the weight?

Non really, considering it depends on the type and density of the material(south) it is fabricated out of.
Question

How do yous estimate the weight past just looking at it?

Call back of the volume and density of the object.

When measuring an object, ever remember to find the volume the correct way. No curt cuts.
You lot can measure the volume by putting the object gently in the water. Make sure it is covered by water. Mensurate the book of h2o pushed out, and that equals to the volume of the object.

Article Summary Ten

While a scale is the most accurate way to find the weight of an object, you lot can get an approximation past using a handmade balance. To showtime, necktie string to the top of 1 loving cup, then necktie the end of the string to the elevation of another loving cup. Balance the heart of the string over a tall, solid object and then the cups can hang freely. Place the object y'all desire to counterbalance in i cup, then fill the other cup with water until it balances with the object. So, measure the amount of water yous put in the cup in milliliters. The number of milliliters of water will equal the number of grams the object weighs. For example, if y'all put in v milliliters of h2o in, that means your object weighs 5 grams. To larn how to find the book of your object, read on!
