Question

Pick out the only vector quantity in the following list:

Temperature, pressure, impulse, time, power, total path length, energy, gravitational potential, coefficient of friction, charge.

Answer 1

Since, Impulse $=$ change in momentum $=$ force/time.

As momentum and force are vector quantities, hence impulse is a vector quantity.

(vector given by their magnitude and direction)
Impulse is vector, it also has a direction.
