Quantity A is velocity if motion is uniformC. Quantity A is displacement if motion is uniformD. Quantity A is velocity if motion is uniformly accelerated.
Answer» Correct Answer - A::C::D When we are calculating velocit of a displacement time graph we have to take slope similary we have to take slope of velocity-time graph to calculate acceleration when slope is constant motion will be uniform. When we are representing motion by a graph it may be displacement time, velocity-time or acceleration-time hence, B may represent time for uniform motion velocity-time graph should be a straight line parallel to time axis. For uniform motion velocity is constant hence, slope will be positive. Hence quantity A is displacement For uniformly accelerated motion slope will be positive and A represent velocity.
