  2. sir in the example near 12:06 minutes after reaction it will decelerates here acceleration is negative but how will the velocity be positive

  3.  
  4. sir no.6 graph since the steepness is increasing therefore angle is decreasing and tanQ is also negative so how the velocity will increase ....? plzzz kindly help
    8 years ago by Yashvardhan Singh Panwar
    Ans 1 ->
    velocity always depends on the steepness. if steepness increases velocity also increases.
    8 years ago by Siobhan Mishra
    Ans 2 ->
    In the 6th graph also the velocity(magnitude) increases as steepness increases(since function of tan increases as it approaches 0)
    8 years ago by Siobhan Mishra
    Ans 3 ->
    but in negative direction(not decreasing). therefore you are mistaken that negative means decreasing.
    8 years ago by Siobhan Mishra
    Ans 4 ->
    Therefore velocity is increasing in negative direction and acceleration is in the direction of velocity(negative) since velocity is increasing. hope you get your answer.

  6. Sir in example 1 of displacement-time graphs the motion of particle below the x-axis or in the negative direction is accelerated so how can it be a straight line?
    9 years ago by Yash Selot
    Ans 1 ->
    there is equal amounts of changes in velocity with time..... and change is negative sign of a number

  8. Sir in 1st e.g. when ball reaches to same height from where it is thrown then from that point how can its graph be a straight line till it reaches the ground ?

  10. Can distance time graph form a triangle with x-axis? I saw it in one of the books and found it difficult to interpret. kindly help
    9 years ago by taniiiroxx
    Ans 1 ->
    At one time there can never be two positions of one particle so triangle can never be obtained above the time axis however triangle can be drawn with one side on time axis.
