Question

The acceleration of a particle at any instant moving along a circular path in a direction tangential to that instant, is known

(a) tangential component

(b) normal component

(c) parallel component

(d) none of the mentioned

This question was addressed to me by my college professor while I was bunking the class.

My doubt is from Acceleration of a Particle along a Circular Path in portion Kinematics & Kinetics of Motion of Machine Kinematics

Answer 1

The correct answer is (a) tangential component

To explain I would say: The acceleration of a particle at any instant moving along a circular path in a direction tangential to that instant, is known tangential component.

The acceleration of a particle at any instant moving along a circular path in a direction normal to the tangent at that instant and directed towards the centre of the circular path, is known as normal component.
