How is average speed defined?
Different from instantaneous speed, average speed is defined as the total distance covered divided by the time interval. For example, if a distance of 80 kilometres is driven in 1 hour, the average speed is 80 kilometres per hour.
What is the definition of average speed in physics?
Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction.
What is average speed one word answer?
We can write: Time = Distance / speed = 1800/40 = 45 hours. Thus we can find the average speed as: Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr.
What is average speed very short answer?
An average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instanteneous speed is the limit of the average speed as the duration of the time interval approaches zero.
What is meant by average speed and average velocity?
Average speed takes distance, that is total length travelled while being measured, while average velocity takes displacement, that is the straight distance from the original position to the final position.
What is meant by average speed class 9?
Average Speed- It is defined as the total path length travelled divided by the total time interval during which the motion has taken place.
What do you mean by average speed what is its SI unit?
The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time. Its S.I. Unit is meter/second or m/s.
What is the average speed of the object?
The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance.
