Which is more impt in projectile motion - KE or Momentum?

a simple physics inquiry

i think both of them are as important as the other

In this case, Momentum is much more important. Momentum will give you information your speed because momentum is a vector while kinetic energy is just a scalar quantity. If you know the mass of the object, with the momentum, you can calculate the velocity, which you know is the speed and direction. Kinetic energy just tells you about the energy the body has because of its motion and nothing with direction. hehehe! Besides, you can calculate the Kinetic Energy from the Momentum. =) hehehe

all parameters are known, initial velocity V, mass M, and range S. which is responsible for making the target fall, assuming of course it is hit? kinetic energy or momentum of the projectile? this is a science thread so mathematical presentation is perfectly alright here.

yeah, but the answer can be found by simple research on the net. And it is something that you should learn your typical physics class. hehehe! I'm just basing everything on the rules for this section ( https://www.istorya.net/forums/scienc...uidelines.html ) because there are many many other references even forums where you can find an answer to this question. hehehe! =)

Interesting question though As I said in my previous post, momentum is much more important in this case. hehehe!

A simulator can help...

getting out of the way of that projectile, IMHO is most important
