phyiscal change
Matter solid
hammering a nail is a physical change, this is because the nail changes shape from being long to being short and in a board for example.
Technology is the use of applied science. So when you use a rock hammer you are applying science to it.
Due to the nature of the very forceful impact of the hammer on the star drill, there is likely to be some metal fatigue leading to the shaft of the star drill becoming uneven or bent, so by rotating it one is able to compensate this uneven stressing on the drill, hereby prolonging the life of the drill due to it remaining straight and true. You rotate the star drill after each blow of the hammer to release the broken debris that has broken off from the last hammer blow. If continuously hitting without turning, the debris would be impacted in the hole and the surface cutting edges on the star drill would not reach a new cutting surface. This is why a hammer drill will hammer and turn at the same time allowing a fresh cutting surface to appear while removing the broken debris.
The hammer exerts a force on the nail; the nail exerts a force on the hammer.
Given a boundless supply of compressed air, concrete can be broken up much easier and faster with a jackhammer than with an icepick or hammer and chisel.
Best practices dictate that if you want any control whatsoever over the size and geometry of the smaller pieces, that you take your diamond to a diamond cutter and pay to have it 'broken' into smaller pieces. If you don't care about the smaller pieces, or the value of the diamond, you could hit the diamond with a hammer and see what happens.
hammer+rock+hard impact= quick change physicaly
Hit it with a hammer.
A hammer does contain a wedge element in its design. The head of the hammer has a flat surface that can act as a wedge to apply force when driving in nails.
The hammer is harder and had smaller surface of impact than hand, the same force transferred to brick at shorter time and higher concentration cause the brick to crack at ease.
only if you hit it with a hammer
big hammer
Um.. a hammer? Or a lever.
It's not advisable use a hammer on a hoe. Garden impliments can be broken that way.
You can change its shape by heating it up, then afterwards, apply pressure. For example, hit it with a hammer.
To put it simply: it was never broken.
