# Homework Help: Understanding the concept of impulse

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.

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 $\Delta p$, then we say that the impulse delivered by the force was of $\Delta p$ kg m/s.
