Impulse+vs.+Momentum


 * impulse || Momentum ||
 * Impulse=F X the change in time || p=mv ||

Impulse and linear momentum are the same, so you may be wondering why bother to have a page dedicated to either of them. Thats obviouse because this is the coolest animation ever and needed to be shared with the world wide web, duh. No, but on a serious not I am putting this on the sight because I think its important to learn the two together. Learning them together may help some find out the small differences. The impulse is the net force applied during a given amout of time. The momentum is the mass time velocity.



So how does this apply to the picture you may ask. Well come on look at whats going on in the picture. How could it not work? The hand is reaching through the soil to get out. Its alive and in action beyong the grave! It is applying a force for a given amount of time, from the point where it once rested in its casket to where it finishes streaching out into the air. That is its impulse. Look at the way we use impulse just in everyday language. It still has the same meaning. When you feel the erge to do something during a given amout of time, same thing the erge is the same as the foce in the above equation. Or you could use the mass of the object, which is the arm, and multiply it by the velocity that it is traveling at to find its momentum. But in the end you will get the same answer.

F X change in time=mv impulse=momentum Tasha
