A particle moves in a plane with constant acceleration in direction different from initial velocity. Can ever the particle have velocity parallel to acceleration? Explain your answer.

A component of initial velocity is in a perpendicular direction to the direction of acceleration. It is given that acceleration remains constant and cannot be reduced to zero.

Velocity will be parallel to acceleration if and only if, component of velocity perpendicular to acceleration is zero.

Therefore the particle moving in a plane with constant acceleration in direction different from initial velocity can never have velocity parallel to acceleration.

Velocity will be parallel to acceleration if and only if, component of velocity perpendicular to acceleration is zero.

Therefore the particle moving in a plane with constant acceleration in direction different from initial velocity can never have velocity parallel to acceleration.
