Momentum is a vector quantity, meaning it has both magnitude and direction. It has been suggested that, since m had already been used for “mass”, the p may be derived from the Latin petere (“to go”) or from “progress” (a term used by Leibniz). The origin of the use of p for momentum is unclear. The SI unit of impulse is Newton-seconds (Ns) or kg m/s. Mass is measured in kg and velocity in ms-1, therefore, the SI unit of momentum will be kgm/s(-1). SI Unit of Momentum As mentioned above, the units of momentum will be the product of the units of mass and velocity. Δ→tF=m(vf)−m(vi) Notice that we have calculated the change in momentum as the initial momentum (mivi) subtracted from the final momentum (mfvf). The impulse-momentum theorem states that the impulse applied to an object will be equal to the change in its momentum. Impulse is equal to the change in momentum ( Δ p \Delta p Δp ) and is sometimes represented with the symbol J. Impulse ( F Δ t F \Delta t FΔt ) Product of the average force exerted on an object and the time interval during which the force is exerted. Impulse is the big force acting for a very small interval of time. Here the huge force is applied on the wall by the car in a very little time interval which we term as an impulse. When the golf ball is hit by the player, it receives a sudden change in momentum. When a football player kicks a ball suddenly with force, the ball shoots away. From the equation, we see that the impulse equals the average net external force multiplied by the time this force acts. F net Δ t F net Δ t is known as impulse and this equation is known as the impulse-momentum theorem. What is the formula for calculating impulse? Impulse is also known as change in momentum. Impulse Formula The Impulse Calculator uses the simple formula J=Ft, or impulse (J) is equal to force (F) times time (t).
