Hi, I read in a textbook that covalent bonds are formed when atoms share an electron. The book gave an example of the H2 molecule.
I'm having trouble understanding how H2 can still bond when the nuclei and electrons are repelling. Shouldn't that cancel the attraction force between the atoms?
if i throw a ball of matter forward in space will it travel faster than light given enough time and space with nothing what so ever to stop it i.e Newtons first law of motion in effect.i figured it should becuase it will have a force to give it a constant acceleration(change in velocity).my...
im reading a chemistry text and its says in daltons law chemicals can not change into atoms during a chemical reaction.but if fusion is a chemical reaction then this is wrong beacuse in stars for example hydrogen combine with hydrogen to form helium .i guest i need a little clarification of...
Alrigh
so Newton is wrong if an object
well
while on a diving board i according to netwon's third law my weight is coming back to me from the diving platorm netforce on me is zero so no acceleration.but where i get confused is when you jump from the diving platform,and the forces become...
yes force has to increase for you to go fast i don't mean to keep from slowing down, if force stay the same ,velocity should stay the same. so if I am given a force of 822N due to my mass in Earth gravity if i were to fall i show fall with a force of 822N
this force that is acting on me is it...
hello I've just started learning physics my question is why do force increase while falling and stay constant while on the ground.i know force is increasing because in free fall things accelerate which according to Newton first law force must also go up. the force of gravity of Earth is 9.8N...
i joined this site in order to get help with physics it seems a great way to get a better understanding of physics.i failed the first physics class i took now I am taking it again in august.
