Question

a particle moves with uniform velocity :

[a] it must be at rest [b] it moves along a curved path [c] it moves along a zig-zag path [d] it moves with zero acceleration

Answer 1

1. A particle at rest cannot be moving (False)

2. An object moving along a curved path is changing it's direction, so it's accelerated motion. (False)

3. Same as 2. (False)

4. a = (v-u)/t = 0 (as v= u) (True)
