Motion In A Plane

Motion in two or three dimensions described by displacement, velocity and

acceleration vectors.

Types of motion in a Plane:

1. Curvilinear motion. Pro!ectile motion". #niform Circular motion

Position $ector %r& ' displacement vector. The displacement of a particle movin(

alon( a plane at a particular point.

$elocity $ector ' a velocity that is tan(ent to the curved path of the particle movin(

alon( the )*y plane.

1. Avera(e $elocity ' the
