Question

area under the velocity-time graph is 40units . what does the physical quantity does this area represent
​

Answer 1

Area under a velocity-time graph signifies distance travelled by object in that particular time interval.

Thus, if the area of the velocity-time graph is 40 units, it signifies that the object has moved 40 units in that bounded time interval.

Quick Trick:

• If a physical quantity is obtained by multiplying two different quantities, the area under the curves gives you the magnitude of the resulting physical quantity.
• If a physical quantity is obtained by dividing two different quantities, then the tangent to the curve gives you the magnitude of the resulting physical quantity.
