Question

A particle is moving with a uniform velocity.Is it necessary that is moving along a straight line.what if the particle moving with a uniform speed instead

Answer 1

Answer:It is necessary that particle should move in a straight line for achieving uniform velocity. This is because moving in circular path will result in continuous change in direction leading to accelarated motion which has non uniform velocity.

If the particle is moving with a uniform speed instead it will travel in a straight line path.

Answer 2

Answer:

1.No it isn't necessary that particle is moving in a straight line with a uniform velocity

2.If particle is moving with uniform speed.. It is necessary that particle is moving in a straight line.

Explanation:

1. Because..velocity has both magnitude and direction i.e. It is a vector. So the particle can be moving in circular motion or in any direction with 0 acceleration

2. Because speed is scalar quantity.. Thus it only has magnitude and not have direction.. So it is necessary for particle to move in a straight line
