Impulse is the integral of force over time, so applying half the force over more than twice the time is greater impulse. It's not a very useful quantity unless you add some conditions, like all of the force is used to increase the object's momentum in the direction of the force. You could apply a large force for years to a tree and never increase its momentum.

Impulse is a function of both the force applied to the object as well as the length of time which that force is applied.
If a small force is applied on an object for a very long time than it is certainly possible for the object to receive a greater impulse than if a large force was applied for a very short time.

impulse=force*time [Newton-sec]
For large impulse we need to increase either the force or time of application. If the time of application is kept constant, it is not possible to obtain greater impulse with a smaller force as compared to a larger force.

J = F(delta)t A small rigidity over a protracted time can equivalent a bigger rigidity over a smaller time. the longer a rigidity is in touch and bigger the rigidity the better the impulse. 500 N vehicle t = 2s 2 hundred N vehicle t = 5s equivalent Impulse.

Hi. Sure, just imagine a bullet going through an apple. Then push the apple with your pinky.
