Question

differentce between instantaneous speed and instantantaneous velocity​

Answer 1

Answer:

instantaneous velocity

for the body moving with variable velocity the velocity measured at any instant( at any given time)is called instantaneous velocity.

instantaneous speed

for a body moving with variable speed continuously with time the speed at any instant is called it's instantaneous speed.

Answer 2

Answer:

Instantaneous speed is the magnitude of instantaneous velocity. Instantaneous velocity is a vector. Instantaneous speed is the magnitude of instantaneous velocity. It has the same value but is not a vector so it has no direction

Instantantaneous Speed

We know that the average speed is for a given time interval is the total distance travelled divided by the total time taken. As this time interval approaches zero, the distance travelled also approaches zero. But the limit of the ratio of distance and time is non zero and is called the instantaneous speed. To understand it in simple words we can also say that instantaneous speed at any given time is the magnitude of instantaneous velocity at that time.
