Answer 2

Assertion: Acceleration of a body can be calculated from velocity-time graph.

Reason: Area of the velocity-time graph gives displacement of a body.​

This Assertion is correct but the Reason is wrong.

• The slope of such a time-velocity graph determines acceleration.

         tanθ=dv/dt

• The acceleration stays unchanged whereas the time velocity graph is the asymmetrical line.

• Positive acceleration happens when the straigh t line's slope is positive.

• Negative acceleration or retardation happens when the straight line's slope is negative.

• Acceleration is equivalent against the slope of such a velocity-time graph. As a result, according to the graph, the body's acceleration is zero.
