Read each statement carefully and state if it is true or false:
A particle in one dimensional motion:
(a) with zero speed at an instant may have non-zero acceleration at that instant;
(b) with zero speed may have non-zero velocity;
(c) with constant speed must have zero acceleration;
(d) with positive value of acceleration must be speeding up.
Look at the graphs (a) to (d) carefully and state, with reasons, which of these cannot possibly represent one-dimensional motion of a particle.
State True or False:
A particle in one-dimensional motion
A.
(a) with zero speed at an instant may have non-zero acceleration at that instant
