Question

The area under acceleration-time graph represents the

• A. initial velocity
• B. final velocity
• C. change in velocity
• D. distance travelled

Answer 1

Answer: (C)

change in velocity

The vertical axis will represent the acceleration of the object. The slope of the acceleration graph will represent a quantity called the jerk. This jerk is the rate of change of the acceleration. The area under this acceleration graph represents the change in velocity. Also, this area under the acceleration-time graph for some time interval will be the change in velocity during that time interval. Multiplying this acceleration by the time interval will be equivalent to finding the area under the curve.

Option C is correct.
