    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.

    You said it. If a force is applied to an object for some time, and that as a result the momentum of the object changed by an amount [itex]\Delta p[/itex], then we say that the impulse delivered by the force was of [itex]\Delta p[/itex] kg m/s.
