Whats the difference between instantaneous and average?

The difference between Average Speed and Instantaneous Speed is that Average speed is stated as the distance covered by the object within a period of time, whereas Instantaneous speed is the accurate speed covered by the object or a body at a given instant of time. Also, instantaneous speed is a scalar quantity.

How is average speed different from instantaneous speed class 9?

Difference between average speed and instantaneous speed: The total distance covered by an object during a certain time span is used to calculate the average speed. The exact speed that an object at motion at a given instant time is the instantaneous speed.

Can average speed and instantaneous speed be equal explain?

Uniform motion of a body is defined as when it travels an equal distance in equal interval of time it is said to be in a uniform motion. So the instantaneous speed can be equal average speed in only one case, when the body travels with constant speed.

Which statement best explains the difference between instantaneous speed and average speed?

What is the difference between constant, instantaneous, and average speed? constant speed is where the speed is the same throughout and instantaneous speed is speed given at any moment and average speed is a total distance traveled divided by the amount of time it took to travel it.

Which equation describes average speed?

One major difference is that speed has no direction; that is, speed is a scalar. We can calculate the average speed by finding the total distance traveled divided by the elapsed time: Average speed=–s=Total distanceElapsed time. Average speed = s – = Total distance Elapsed time .

What is instantaneous speed formula?

Instantaneous speed=|v(t)|. Instantaneous speed = | v ( t ) | . If a particle is moving along the x-axis at +7.0 m/s and another particle is moving along the same axis at −7.0 m/s, they have different velocities, but both have the same speed of 7.0 m/s.

What are two differences between average speed and average velocity?

1. Average speed is a scalar quantity, while average velocity is a vector quantity. 2. Average speed takes into account the total distance traveled, while average velocity is concerned with the displacement between two points.

What is the difference between average speed(u) and instantaneous speed(v)?

INSTANTANEOUS SPEED(v): it is a speed of an object wrt to an observer in a very short time .It is better to say it is the speed of an object at a moment. Average speed(u):It is very simple. u=total distance travelled/total time required. Definitions some times does not help us .

Is instantaneous speed constant for an object?

Instantaneous speed is not constant for an object or a body. And it is measured with the help of the vehicle-installed speedometer. The speedometer tells the exact accurate value of the speed at that particular instant of time. The value of the instantaneous speed is greater than or equal to zero.

Is 100 km/h an average speed or instantaneous speed?

It has many instantaneous speeds and 100 km/h is the average of those instantaneous speeds. We can follow the same steps used in the definition of average and instantaneous speed while defining average and instantaneous velocity.

What is an example of instantaneous velocity in physics?

An example of this is a car driving down the highway at a constant speed of 60 miles per hour. The average velocity of the car is 60 miles per hour, and no matter what time you measure the instantaneous velocity, it will always be 60 miles per hour.
