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.
The vector quantity is impulse.
NOTE: Impulse is defined as the change in momentum. It gives the effect of a force over a period of time.
J = Δp = FΔt
Where, J is the impulse
P is the momentum
F is the force
t is time
Here, p and F are vectors so that J is also a vector.
