If the graph plotted between displacement versus time of a moving object is a straight line parallel to the time axis then the acceleration of the moving object will be

If the graph plotted between displacement versus time of a moving object is a straight line parallel to the time axis then the acceleration of the moving object will be Correct Answer Zero

Correct option-2

Concept:-

  • The Displacement-time graph is nothing but a plot between displacement and time. 
  • The displacement of a moving object is a vector quantity so it can be both positive and negative.
  • The graph between displacement and time (x-t) is very useful in numerical analysis.
  • The x-t graph gives us the idea of velocity and acceleration.
  • By the slope of the x-t graph, we can find the velocity.

 

Explanation:-

  • The slope of the tangent in a graph plotted between two physical quantities is the rate of change of that quantity represented by the Y-axis with respect to the change in the quantity represented by the x-axis.
  • The slope is nothing but the tangent angle made by the tangent line to the curve with the x-axis.
  • For displacement- time graph, the slope of the x-t graph determines the instantaneous velocity and its unit is m/s.

  • The displacement time graph for an object at rest is a straight line with zero slopes.
  • The displacement time graph for an object having uniform motion in a straight line with a non-zero slope.
  • The displacement time graph for an object with uniform acceleration is a parabola.
