The impulse of a force is defined as the product of the average force and the time interval for which the force acts on the body. Q2 What is the unit of impulse? The SI unit of impulse is Newton second. Q3 What is the relation between impulse and momentum?
A microphone in which the sound waves move a conductor back and forth, cutting magnetic lines of force and producing an electrical output of the same frequency and proportional to the amplitude of the sound waves. inductor-type synchronous motor A type of synchronous motor having field magnets ...

Impulse, Force and Time force / N time / s force / N time / s impulse = area under force-time graph Example 1 A 50 g golf ball is hit off the tee by a force which varies with time as shown. force / N time / ms Calculate the speed of the golf ball off the tee. ...
Since impulse is thrust times ∆t, divide by ∆t to get the average thrust (force). Result: thrust = (speed of gas relative to nozzle) times (mass of gas ejected per unit time) thrust Physics 1D03 - Lecture 25 Summary • Definitions: momentum, impulse • Newton’s Second Law,...
SI system of units where mass is measured in kg and velocity in ms -1 the force would be in Newtons. Hence both impulse and momentum have units of newton-seconds (Ns). Example 1. A particle of mass 0.75kg has velocity 16i – 12j ms -1 when it receives an impulse of magnitude 2 ...
the nozzle jet and the rotational plane of the runner. The water from the penstock is transformed into a high speed jet through the nozzle. The water is directed obliquely to one side of the runner and discharges at the other. The dynamic force of water flow makes t...
Force applied over time creates an impulse, a change in momentum. Impulse is defined in classical mechanics as aforcemultiplied by the amount of time it acts over. In calculus terms, the impulse can be calculated as the integral of force with respect to time. The symbol for impulse isJor ...
