Examples of Impulse
Impulse is:
- The gun powder accelerating the bullet in a rifle,
- The bow string accelerating the arrow,
- The rocket engines accelerating the shuttle,
- The fist accelerating the punching bag.
In general impulse is the force applied to a given object with a given mass for a given period of time. This will decide the amount of acceleration, final velocity and the kinetic energy stored in that object. If you know momentum and the mass of the object you do not need acceleration to calculate final velocity. Momentum is conserved. If an object slows down a certain amount of energy is transferred from the object to the environment. This transfer could be in the form of acceleration or deceleration of another object or heat due to friction or collision.

“It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
—G.C. (Georg Christoph)

—G.C. (Georg Christoph)
“In benevolent natures the impulse to pity is so sudden, that like instruments of music which obey the touch ... you would think the will was scarce concerned, and that the mind was altogether passive in the sympathy which her own goodness has excited. The truth is,—the soul is [so] ... wholly engrossed by the object of pity, that she does not ... take leisure to examine the principles upon which she acts.”
—Laurence Sterne (1713–1768)
