Detailed explanation-1: -Instantaneous speed is a measurement of how fast an object is moving at that particular moment. Instantaneous velocity is a vector quantity that includes both the speed and the direction in which the object is moving.
Detailed explanation-2: -Instantaneous velocity is defined as the rate of change of position for a time interval which is very small (almost zero). Measured using SI unit m/s.
Detailed explanation-3: -What you see on the speedometer of a car is the speed at that instant or moment – the instantaneous speed. It’s the speed right now . One way to find this instantaneous speed is to measure the rate of rotation of the wheels.
Detailed explanation-4: -A speedometer or speed meter is a gauge that measures and displays the instantaneous speed of a vehicle.
Detailed explanation-5: -The speed unit is metres per second (m/s). The instantaneous speed is never less than or equal to zero.
