Compression forces crush a material by squeezing it together.
This is compression. Compression is one of the 4 internal forces acting on a structure. Squeezing a structure implies that it is compression.
If the force is decreased, it will likely become smaller, and perhaps also lesser as well. Too.
compression and tension Compression is a squeezing force, while tension is a pulling force.
The principal of inertia merely says that a body will remain ar rest until moved by a force. The force required to lift a bottle has to be equal and opposite to the force of gravity pulling it down which is proportional to its mass. So the more mass in the bottle the more force required to lift it.
The volume inside the bottle gets smaller.
Upthrust
buoyancy
Adding magnesium powder
Upthrust
density water's density is 1.00 g/c3 and the plastic bottle is less (plus it also has to with buoyancy)
Compression
Compression forces crush a material by squeezing it together.
Heating the air inside causes the bottle to expand-the presure inside is enought o force the walls out,
All liquids and and gases have pressure. Pressure is also a force but does not depend on area it acts. Pressure is arising from its own weight. The molecules in liquids and solids areattracted downward due to earth's mass(gravitational force). The impact of this gravitational force per unit area is the pressure. if there is a liquid or gas there must be pressure. the magnitude of pressure inside a plastic bottle depends on the weight of the air in it.
When you are squeezing a sponge you are applying the push force from all the sides of the sponge and as a result it will squeeze.
This is compression. Compression is one of the 4 internal forces acting on a structure. Squeezing a structure implies that it is compression.
