what is the difference between instantaneous and average speed?
10228
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.

Figure 3.6 In a graph of position versus time, the instantaneous velocity is the slope of the tangent line at a given point. The average velocities –v=ΔxΔt=xf−xitf−ti v – = Δ x Δ t = x f − x i t f − t i between times Δt=t6−t1,Δt=t5−t2,andΔt=t4−t3 Δ t = t 6 − t 1 , Δ t = t 5 − t 2 , and Δ t = t 4 − t 3 are shown.

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.

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.

Velocity is one kind of rate of change. It is the rate of change of position with respect to time. Rate of change is more general and includes velocity as one example. The word "instantaneous" has does not alter any of this.

The instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of x with respect to t: v(t)=ddtx(t). v ( t ) = d d t x ( t ) .

Average speed is calculated by dividing the distance of an object in motion by it's time. ... The difference between speed and velocity is that velocity has direction. Both of them involve distance and time, but only velocity involves direction.

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.

if the measurement is taken over a very short time interval, we are measuring the instantaneous throughput. if the measurement is taken over a long time interval, for example, the transfer of a whole group of files, we are measuring the average throughput.

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 instantaneous velocity is the specific rate of change of position (or displacement) with respect to time at a single point (x,t) , while average velocity is the average rate of change of position (or displacement) with respect to time over an interval.

The instantaneous rate is the rate of a reaction at any particular point in time, a period of time that is so short that the concentrations of reactants and products change by a negligible amount. The initial rate is the instantaneous rate of reaction as it starts (as product just begins to form).

No, the average speed is not always equal to magnitude of average velocity vector. The average speed is the distance traveled divided by time interval whereas the the average velocity vector is the displacement vector divided by time interval.

Constant velocity is very different from average velocity. If an object traveled at 35 m/s for 20 s, it would travel the same distance in the same time as the previous example but in the second case, the object's velocity would always be 35 m/s.

A rate of change tells you how quickly a quantity is changing. For example, the speed that you are moving at is the rate of change of your position. An average rate of change tells you the average rate that something is moving at over a period of time.

Average Rate is the rate of reaction calculated for a long time interval. It is defined as the amount of change/time taken. ... Instantaneous Rate is the rate calculated at any instant during the reaction.

Average velocity is a vector quantity, meaning it includes the magnitude and the direction of the object. While average speed is a scalar quantity which only has the magnitude of the object. ... The unit of measurement of velocity is the same as that of speed, but its a derived unit.
