Yes. The glass is still glass.
you can not change it back
Bounce is a change of direction after hitting the ground.
Physical Impact means that some thing has changed in appearance. Like if you fell on the ground and cut yourself that is an impact that happened physically.
A falling snowflake or raindrop does not accelerate as it approaches the ground because their mass doesn't change. The form is not affected throughout the fall so it is already approaching the ground at terminal velocity. Hope this helps.
No. The change in potential energy and momentum both depend on the mass of the object, and the metal ball and plastic ball have different masses. What's the same for both of them is their acceleration while they fall, the time they take to reach the ground, the moment when they hit the ground, and their speeds when they hit the ground.
air resistance will increase the time for an object to fall to the ground
No. That is a physical change.
It is a PHYSICAL change.
A metal Surface being ground is a physical change, not a chemical change.
If you mean ground flour, then no. Grinding flour is a physical change because there is no change in chemical composition.
Yes, grinding is a physical change because the chemical composition of the substance does not change.
Physical, the chemical properties of the wheat are still the same.flour is ground by a physical change
yes, theres is not change to it's molecular structure
The act of burying garbage itself is not really a physical change. If the garbage was crushed, that would be a physical change. When the garbage decomposes in the ground, that is a chemical change.
That woul be a physical change. Gosh this is the eighth question
Chemical Change
Powdery is an adjective which not require any change!You can have a physical change where a large lump of some substance is ground into powder. Or you can have a chemical change (eg magnesium burning) which leaves a powdery residue.
Cooling, and changing from a liquid to a solid are physical changes, not chemical changes. The chemical composition of the paraffin does not change.
