CONSERVATION OF LINEAR MOMENTUM

1. Learning Objectives
The main objectives are to: Investigate the linear whim of two Cars before and after an elastic smash defend the principle of linear whim and observe Determine the coefficient of return of each collision

2. Introduction
Generally, momentum is conserved during collisions. The momentum of an object is the harvesting of its mass and its fastness. By the law of preservation of Momentum, the sum of the momentum in one system before collision (or otherwise interaction) equals the sum of the momentum after collision.

m A (v A )1 + mB (vB )1 = m A (v A )2 + mB (vB )2
In each impact, a deformation and restitution must occur. By elimination the impulses during those period, the coefficient of restitution (e) can be expressed in terms of the masses initial and final velocities as

e=

(v B )2 ? (v A )2 (v A )1 ? (v B )1
? mv post ?collision ? mv pre?collision

where (v A ) 1 > (v B ) 1 &

(vB ) 2 > (v A ) 2

The formula is effectively the same as infra:

e=

when the values of mv are taken as absolute

Energy-loss can be calculated as: (1 ? e) × 100 %

4. Experimental Procedure
For this activity, execution sensors will measure the motion of two Cars during an elastic collision. The Science Workshop program calculates stain for both Cars. A graph of the motion for both Cars reveals their velocity before and...If you want to get a full essay, point it on our website: Orderessay
