what is the difference between instantaneous speed and average speed?
91024
It is different from average speed because average speed is measured by the total time of a journey divided by the total distance. In contrast, instantaneous speed measures the smallest interval possible divided by the time it took to move that distance.

Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr.

Speed, being a scalar quantity, is the rate at which an object covers distance. ... On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

Velocity is the rate at which displacement changes with time. It is a vector, too. The average velocity over some interval is the total displacement during that interval, divided by the time. The instantaneous velocity at some moment in time is the velocity of the object right now!

Speed is the rate of change of distance(basically how much distance(m) has been covered in a particular time(s)). Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of velocity per unit of time.

What is average speed? Average speed is calculated by dividing the total distance that something has traveled by the total amount of time it took it to travel that distance. Speed is how fast something is going at a particular moment. Average speed measures the average rate of speed over the extent of a trip.

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.

Speed commonly refers to the constant rate of change over a distance. ... Rate is a description of change over time. It doesn't have to do with distance (as with speed).

the rate at which the velocity of an object changes. average acceleration. the change in an object's velocity during a measurable time interval, divided by that specific time interval. instantaneous acceleration. the change in an object's velocity at a specific instant in time.

The rate of doing work is called power. The basic difference between average and instantaneous power is that average power is the ratio of total work and total time. While instantaneous power is the limiting value of average power.

Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time. Movement can be shown in distance-time and velocity-time graphs. Physics (Single Science)

The speed is the time rate of change of the distance. If 'D' is the distance of an object in some time 'T', the speed is equal to, s = D/T. It has the same units as velocity.

Answer: Average velocity and average speed are not always the same as average velocity is related to the displacement of a body whereas average speed is related to the distance travelled by a body. Average velocity is determined by dividing the total displacement of a body with time.
