Expert Answer:

  • Graph A is a parabola. The Body is moving with uniform acceleration. The slope of the time-displacement curve is increasing with time. Hence, uniform force is acting.
  • In graph B, the body is moving with uniform retardation. The slope of time-displacement curve is decreasing with time. Hence, uniform force is acting , but in the opposite direction.
  • Graph C is a straight line. The Body is moving with uniform velocity. Hence, force on a body is zero.
  • Graph D is a straight line parallel to the time axis which shows particle is at rest. Hence force along the x axis is zero.
  • Graph E is a parabola. The motion of a body is vertically downwards and the acceleration is uniform. The slope of time-displacement curve is increases with time. Hence, the uniform force is acting.
