Question

what is instantaneous speed?Give one example​

Answer 1

Answer:

Explanation:

Instantaneous velocity is defined as the rate of change of position for a time interval which is very small (almost zero).

...

Difference between Instantaneous Speed and Instantaneous Velocity.

Instantaneous speed Instantaneous velocity

Instantaneous speed is a scalar quantity Instantaneous velocity is a vector quantity

Answer 2

Answer:

The rate of change of distance of an object with respect to time is known as instantaneous speed.

It is denoted by capital letter V

V=change in position/change in time

V=delta x / delta t

Examples are : A car moving along a distance of 10m in 2sec find the instantaneous speed?

sol: x=10m, t=2sec

V=x/t

=10m/2sec

=5m/sec

therefore the instantaneous speed is 5m/sec.
