1) What is velocity (v)? a) Rate of change of displacement with respect to time b) Rate of change of distance with respect to time 2) Which formula correctly represents velocity? a) v=dt/ds​ b) v=dt/dv​ 3) If motion to the right is taken as positive direction, positive velocity means:. a) The particle is moving to the left b) The particle is moving to the right 4) When velocity is zero (v = 0), the particle: a) Is moving with constant speed b) Is at instantaneous rest 5) Negative velocity (v < 0) indicates that the particle is: a) Moving to the right b) Moving to the left 6) A particle has zero velocity at a certain instant. This means: a) It stops momentarily b) It has zero displacement 7) Velocity is zero at the point of: a) Constant acceleration b) Maximum or minimum displacement 8) Which statement about velocity is correct? a) Velocity has both magnitude and direction b) Velocity has magnitude only 9) If a particle changes direction, its velocity: a) Becomes zero permanently b) Changes sign 10) Velocity tells us: a) The direction of motion of the particle b) The position of the particle from point O
