Is the impulse a vector quantity?

Answer 1

Yes, impulse is a vector quantity.

#J = F_(avg)*Deltat# #J = Deltap# #J = p_(2) - p_(1)#

(#J# is impulse, #p# is momentum, and #t# is time)

In the first equation, the average force is a vector quantity, which means that impulse must also be a vector quantity because a scalar times a vector is always a vector.

The second and third equations describe impulse in terms of momentum. Momentum is a vector since it is the product of velocity and mass, therefore impulse must be a vector quantity because the difference of two vectors is still a vector.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
