Curvilinear Motion

• in discussing curvilinear translation, the bodymay be assumed to be concentrated at its center of

  gravity and treated as a particle as in the case of  rectilinear translation
• In curvilinear motion, the displacement vector  will change in both magnitude and inclination
• In curvilinear motion ,  the velocity is always  directed tangent to the curved path of the motion, the

  acceleration is not tangent to the path
• In curvilinear motion,  It is evident that the change in displacement ∆𝑠

  is due to combined change in the magnitude and inclination of these displacement vectors
• Projectile motion follows a parabolic trajectory
• The vertical component of projectile is under constant downward gravitational acceleration and the horizontal component is at

  constant velocity
