MOMENTUM

LINEAR MOMENTUM

DEFINITION:is the product of mass and velocity. It is represented by P. hencep= mass (kg) x velocity (m/s)p=mvthe S.I unit of momentum is kgm/s or NSIt is a vector quantity I.e. have magnitude and direction

Example

The magnitude  of an object is 5kg  and moves on a straight line with velocity of 5m/s . Calculate its momentumsolution:p=mass x velocityp= 5 x 5=25 kg.m/s

Example 2

An Aichi D3A bomber mass (3600 kg) departs from its aircraft carrier with a velocity of 85 m/s due east. What is its momentum?solution:p= mass x velocityp= 3600 x 85=306000kg.m/s
