Kinetics of curvilinear translation

• When a particle moves along a curved path which is known, the

  equation of motion for the particle may be written in the tangential,

  normal, and binormal directions.
• So if 𝑇 acts in the direction of

  motion, the particle’s speed will increase, whereas if it acts in

  the opposite direction, the particle will slow down
• In Centripetal force , It is caused by N which always acts int he positive N direction, i.e., toward the path’s  center of  curvature, .
• These inertia forces are known as the centrifugal inertia force

  or simply centrifugal force (or reversed normal effective

  force) and the tangential inertia force (or reversed tangential

  effective force).
• A pendulum is a weight suspended from a pivot point that is free to swing back and forth under the influence  of gravity
• Because the string generates a cone while in motion, the  system is called a conical pendulum
• Dynamic equilibrium is created by applying the centrifugal force acting radially outward from the center of the path
• The tension 𝑇 is also obtained from the force  polygon.
