Can a particle in one- dimensional motion have zero speed and a non-zero velocity ?

Can a prticle in one- dimensional motion have zero speed and a non-zero velocity ?

Figure gives the x-t plot of a particle is one dimensional motion. Give the signs of position, velocity and acceleration of the particle at t = 0.3s

For a particle in one dimensional motion, the instantaeous speed is always equal to the magnitude of instantaneous velocity. Why ?

Can a paticle have (i) zero speed and non - zero velocity ? (ii) constant velocity but a varying speed ? (iii) constant speed but a varying velcoity ?

A body in one dimensional motion has zero speed at an instant. At that instant, it must have

Figure shows the position the graph for a particle in one dimensional motion. Which of the graphs in fugure represent the variation in the velocity of the particle with time ?

Can a body have uniform speed but non-uniform velocity ?

Read each staremnt below carefully and state with reasons and expamples if it is true or false , (a) with zero speed at an instant may have non-zero accelration at that instant (b) with zero speed may have non-zero velocity (c ) with positive speed must have zero accleration (d) with positive value of acceleration must be speeding up.

When does a particle motion have uniform speed?
