    Yar wht abt when we have to draw a v/t graph based on d/t graph...The prob here is the sudden shift if d/t graph as it goes from having a gradient to 0 gradient.In the v/t graph this means tht the speed suddenly plummets.Does this mean we have to break the graph of v/t at tht point when the...

    Oh sorry wrong reference to amd..wht I meant was tht he was right in telling u tht graphs had to be a curve at those stages...And tht straight line graps wud of course not score full marks...Again ,unappreciated means tht the students did not consider the acceleration factor in speed time graphs...

    Maths, Addmaths and Statistics: Post your doubts here!

    amd is right,complemented by ER;ER says tht "it was not appreciated tht acceleration means a curve" or sth like tht.So it means tht we have to consider the acceleration factor in speed time graphs and a curve WUD be produced.Not appreciated means tht many did not consider the factor of...
