Question

Which of the following situations is impossible to have?justify your answer.
a)object moving with variable velocity but fixed acceleration.
b)object moving with uniform velocity but non uniform acceleration.
c)object moving with uniform speed but variable acceleration.

Answer 1

Dear Student,

Object moving with uniform velocity but non uniform acceleration is impossible.

Option (a) is common. A freely falling body, the velocity of the falling object increases every second but acceleration due to gravity is fixed.

Option (c) is possible. An object is in uniform circular motion, i.e., it has fixed speed but direction of an object is changing every moment.
