what can you put in a bucket to make it lighter?

Answer 1

The was a man at a lunatic asylum walking around with a bucket held upside down. When asked why he said:

"They think I am mad but if I turned it up the right way someone would put something in it for me to carry!"

Answer 2

Let me give you a complicated answer:

I'll assume you're talking about weight (which is the gravitational force that acts on an object / body) and not mass (which is the measure of inertia possessed by an object / body).

If we're talking strictly about reducing the weight of a bucket, then there are only 2 ways to reduce its weight:
1. reduce its mass by removing some of the material (but then it wouldn't be the same bucket)
2. bring it to somewhere where the gravitational field strength (amount of gravitational force per unit mass) is less, say on a smaller planet (eg mercury or mars) or on a moon.

A third answer you may get would be:
Put a lighter than air object (eg a helium filled balloon) in the bucket or tie one to it.

This third method would not be in all strictness, correct. Actually, when we put anything in or tie anything to the bucket, its weight would increase (yes, even the lighter than air balloon).

"Why?", you ask.

Well, strictly speaking, what you measure when you stand on a "weighing machine" is not actually your weight, but your "apparent weight", which is the normal force that acts (upwards!) on you.

The "weight" which your weighing machine measures is actually your weight minus the upthrust (weight of the air that your body displaces). Helium balloons float because their weight is less than the air they displace.

(For a better idea of upthrust, its the reason why we feel lighter when we jump into a body of water - we've displaced some water, and there is an upward force acting on us as a result)

To make it clearer, let's imagine if we could remove all air from the earth's surface, the helium filled ballon would no longer float. It only floats in air because its actually lighter than air.

So there are only 2 ways.

Cheers.

Answer 3

First find the weight of the bucket without placing any thing inside.

Take any object whose weight is more than the measured weight.

Place this inside the bucket. Now your bucket is lighter than the object placed inside.

Answer 4

Anti-matter!

Answer 5

I guess if you turned it upside down and filled it with He or H it would make it lighter.

Answer 6

A Hole.. That Ones Old

Answer 7

Would have to be a hole. The missing metal or plastic would make it weigh less.

Answer 8

u talking abt full bucket with water or empty...if full then obviously i will make a hole but if not then......:)

Answer 9

a hole?? i was tinking of anti gravitons or sth.. haha

Answer 10

dont you check asked questions ,
this question is asked almost every day
please try to be original.
or do you have a hole in your head.
