Question

Define speed average speed and instantaneous speed​

Answer 1

Answer:

Instantaneous speed is found by taking the absolute value of instantaneous velocity, and it is always positive. Average speed is total distance traveled divided by elapsed time. The slope of a position-versus-time graph at a specific time gives instantaneous velocity at that time.

Answer 2

Explanation:

Average speed:

The "total distance" traveled by a "body in a definite interval of time" is known as "average speed".

By derivation it is represented as,

Average speed = Total time taken / Total distance

Speed is a scalar quantity. So it does not have a unit. the "instantaneous speed" is the "limit of the average speed" as the "duration of the time interval" approaches zero."
