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.

“Histories are more full of examples of the fidelity of dogs than of friends.”
—Alexander Pope (1688–1744)
“There are many examples of women that have excelled in learning, and even in war, but this is no reason we should bring ‘em all up to Latin and Greek or else military discipline, instead of needle-work and housewifry.”
—Bernard Mandeville (1670–1733)
“Public administrators would get along better if they would restrain the impulse to butt in or be dragged into trouble. They should remain silent until an issue is reduced to its lowest terms, until it boils down into something like a moral issue.”
