Question

The basic difference between uniform linear motion & uniform circular motion is

• A. Uniform linear motion is accelerated motion and uniform circular motion is non- accelerated motion
• B. Uniform linear motion is non- accelerated motion and uniform circular motion is accelerated motion
• C. Uniform linear motion is along the radius and uniform circular motion is along the tangent
• D. Uniform linear motion is along the tangent and uniform circular motion is along the radius
• E. Uniform linear motion is along the radius inwards and uniform circular motion is along the radius outwards

Answer 1

The correct option is B

Uniform linear motion is non- accelerated motion and uniform circular motion is accelerated motion

Uniform Linear Motion: Velocity is constant & thus it is a uniform motion. Acceleration is zero. Uniform Circular Motion: Velocity is not constant due to continuous change in Direction & thus it is not a uniform motion. Acceleration is called Centripetal acceleration.
