Hey. Im having a little trouble understanding the concept of impulse. The textbook i am using doesnt really shed much light onto the topic. I know that impulse is equal to the change in momentum of an object, or the product of a force applied to an object and the time it is applied for. If somebody could please basically explain what impulse is, that would be great. I am a year 11 student in Australia, so i only really need to understand on a basic level. Thanks, Dan.
