Question

The area under a speed-Time graph is represented by the unit: a- m2 b- m c-m3 d- 1/m

Answer 1

Answer:

it should be b) m

Explanation:

Since rate of change in distance over time is speed , Area under speed - time graph will give us distance . whose unit is metre . the area under speed-time graph is the distance travelled by the body within that time period or with the speed...it would be displacement if speed was velocity

Answer 2

Therefore the unit of the area under a speed-time graph is 'meter'. ( Option-b )

Given:

The area under a speed-time graph is given.

To Find:

The unit of the area under a speed-time.

Solution:

The given question can be solved as shown below.

The area under a speed-time graph = Speed × Time

⇒ Speed = Distance / Time ⇒ Distance = Speed × Time

So the area under a speed-time graph ( Speed × Time ) gives the distance.

Hence the units of Distance are meters or centimeters.

Therefore the unit of the area under a speed-time graph is 'meter'.
