King Fahd University of Petroleum Minerals
• Mechanical Engineering
• Dynamics ME 201
• BY
• Lecture 39

2
Planar Kinetics of a Rigid Body Impulse and
Momentum
• Objective
• To develop formulations for the linear and
angular momentum of a body
• To apply the principles of linear and angular
impulse and momentum to solve rigid-body planar
kinetic problems that involve force, time, and
velocity.

3
Newtons Second Law
Principle of linear impulse and momentum equation
4
Linear Momentum
• Measure of impact effect
• Compare
• bullets with small mass and high velocity
• Ship with huge mass and slow velocity
• L is a vector -- points in same direction
as v
• Unit kg.m/s or slug.ft/s

5
ANGULAR MOMENTUM
• For a point object the angular momentum is

Units - kg.m2/s or sl.ft2/s It is a vector. Here
the vector is pointing toward you. Using
right-hand rule
6
Angular Impulse and Momentum Principles
7
Moment of Inertia
• This mass analog is called the
• moment of inertia, I, of the object
• r moment arm
• SI units are kg m2

8
Angular Momentum
9
Angular Momentum
• Measure of Rotational effect
• H is a vector quantity in the direction of w
• Unit kg.m2/s or slug.ft2/s
