Impuse is change in momentum and is a vector quantity having the same direction as force. My question is, can impulse always be positive or can be negative? In F-t graph, the area under the curve is impulse, can this be negative?
Homework Answers
We know impulse is F*t and also
Impulse=change in momentum
If final speed is less than initial speed,then change in momentum is negative so impulse will also be negative.So if force applied is opposite to motion,impulse will be negative

How are momentum and impulse related? Question 1 options: They are not related Impulse is equal but opposite to momentum Impulse is equal to the change in momentum Impulse is equal to momentum What do we mean by the statement that momentum is a vector? Question 2 options: You may assign negative numbers to vectors in the opposite direction. All of these are true. When you add momentums, the direction is important, and negative numbers or trig may be needed....
