Example of Leftward Acceleration

6

two-dimensional motion

• General Vector Properties• Polar Vectors: r and Azimuth Angle• r, r, v, a in two dimensions• Projectile Motion• Centripetal and Tangential Acceleration

7

Dynamics

• Newton’s Three Laws of Motion• Net Force and Force Diagrams• Mass and Weight• Normal Force• Friction• Tension• Circular Motion• Drag Forces

8

Newton’s First Law: constant velocity unless or until acted non-zero Net Force.

Newton’s Second Law:

mF

a

Newton’s Third Law: all forces are interactions, same size, opposite direction

9

Force Diagrams

10

Force Conventions

• N – normal force of contact• f – frictional force of contact• W – gravitational force of attraction• M – magnetic force• T – tension force• Example: N12 = normal force on “1” due to

contact with object “2”
