Derivation Of Centripetal Acceleration

Derivation Of Centripetal Acceleration

Centripetal acceleration is the rate of change of tangential velocity. The net force causing the centripetal acceleration of an object in a circular motion is defined as centripetal force. The derivation of centripetal acceleration is very important for students who want to learn the concept in-depth. The direction of the centripetal force is towards the center, which is perpendicular to the velocity of the body.

The centripetal acceleration derivation will help students to retain the concept for a longer period of time. The derivation of centripetal acceleration is given in a detailed manner so that students can understand the topic with ease.

The centripetal force keeps a body moving constantly with the same velocity in a curved path. The mathematical explanation of centripetal acceleration was first provided by Christian Huygens in the year 1659. The derivation of centripetal acceleration is provided below.

Centripetal Acceleration Derivation

The force of a moving object can be written as

  1. nice way to study physics

  2. when we form the triangle why is the v1 vector negative?

    1. QP is the direction of the +v vector. The derivation uses PQ, and hence -v.

    2. Its because in order to add v1 and v2 vectors vectorially using triangle method ,v1 vector has to attach its head to tail so as to obtain resultant vector delta v
