What is the difference of speed from average speed in physics?

Answer 1

Average speed allows you to change the instantaneous speed throughout the travel time, while during constant speed, one keeps there instantaneous speed at the same number
Average speed is when a car is moving with a speed of 25 miles per hour. Constant speed is speed maintained consistency over time.

Answer 2

Average speed is calculated by dividing the total distance traveled by the total time taken, while speed refers to the rate at which an object covers distance. The difference lies in how average speed provides a single value that represents the overall motion, whereas speed can vary at different points during the motion.

Answer 3

Instantaneous speed is the speed you are doing at one particular time.

Average speed is the speed at which you managed to complete an entire distance (journey)

For instance if you went on a 60 mile journey and completed this in 1 hour, your average speed would be 60miles an hour. However for part of the journey you may have had to stop at traffic lights (when your instantaneous speed would be 0 miles an hour) and for other bits of the route you may have been driving at 70 miles and hour.

Answer 4

instantaneous speed is the exact speed at a moment in time. average speed is the overall average over a unit of time. for example, say you were driving to the store which was 10 miles away and it takes you 30 minutes to get there. your average speed would be 20 miles an hour because you went 10 miles in 30 minutes. however it is highly unlikely you went exactly 20 mph the whole time. your speed would have varied throughout the trip. your speed on your spedometer at any given moment on your trip was your instantaneous speed

Answer 5

Speed is the rate of change of distance per second (or unit time). Average speed is total distance over total time.

If an object moves at 80km/h for 2 hours then 40km/h for the next 2 hours, the speed of the car could be 80km/h (first two hours), 40km/h (last two hours) or 0km/h (at the start).

Answer 6

One can think of a racing car making one lap around a car racing track.

During the race the speedometer will be indicating the speed the car has at a given moment. This is the "instantaneous speed" v(t). It is a function of time, meaning

that it varies in time.

If we now take the length of the track L and divide it by the time t the car took to

accomplish one lap, then we have the average speed, vav = L/t, of the car during a

lap around the track.

Answer 7

the average speed is the speed you calculated when you have different speeds at different points or distances.

It is different from speed because average speed has many speeds averaged into one speed ..while speed is specifically only one.

Speed is instantaneous speed, whereas average speed is the average of the instantaneous speeds over an interval (time).

Answer 8

The average speed of an object is the total displacement (change in location) divided by the total time taken. However, the speed can be changing throughout the time period and the [instantaneous] speed of an object is the derivative of the displacement with respect to time. It may be considered as the average speed over smaller and smaller periods of time.

Answer 9

Average means a median of several speeds. Speed is the speed at specific exact time.

Answer 10

If you travel for an hour at 60mph then travel another hour and 50mph your average is 55mph. Your speed difference is 10mph.
