Kinematics & Linear Motion - Slides

Continuous Motion

• We define particle’s position at any instant, relative to the origin, $O$ by:
  The position vector $r$,
  Or the scalar $s$
• The total distance travelled by the particle is $s_T$
  • Scalar that represents total length of the path of the particle

Curvilinear Motion - Slides

General Curvilinear Motion

• A particle moving along a curved path undergoes curvilinear motion
  • Motion is described using 3D vectors
• A plot of the locus of points defined by the arrowhead of the velocity vector is called a hodograph
  • The acceleration vector is tangent to the hodograph,
  • But generally not tangent to the path function
• The direction of $v$ is tangent to the path function
