Question

The graph between the displacement S and time t for a particle moving in a straight line is shown in figure. During the interval OA, AB, BC and CD the acceleration ofthe particle is

• A. + + + +
• B. - 0 + 0
• C. + 0 - +
• D. - 0 - 0

Answer 1

The correct option is B - 0 + 0

The slope of the Displacement-Time curve is Velocity.

During OA - slope decrease that means decelerated motion.

During AB - slope is constant that means zero acceleration.

During BC - slope is increasing that means accelerated motion.

During CD - slope is constant that means zero acceleration.
