## What is meant by average speed and uniform speed?

Average Speed = Total distance travelled / Total time taken.

eg.

For a car which travels a distance of 100 km in 4 hours , the average speed is 100/4 =25 km/hr.

Uniform Speed:- A body has a uniform speed if it travels equal distances in equal intervals of time, no matter how small these intervals may be..

## What is the difference between speed and average speed?

Difference between speed and velocity If a car is said to travel at 60 km/h, its speed has been specified. … This is because the average velocity is calculated by considering only the displacement between the starting and end points, whereas the average speed considers only the total distance travelled.

## What is the formula of uniform speed?

Uniform Speed: The body has uniform speed if it covers equal distances in equal intervals of time however short the interval may be. In the equation, S=v t v is the average speed of a body during time t.

## What is the time symbol?

HourglassSymbol of Time is The Hourglass.

## What is the symbol for average speed?

## What are the types of speed?

There are five types of speed and they are:Uniform speed.Variable speed.Average speed.Instantaneous speed.

## Who invented speed?

Galileo GalileiThe Italian physicist Galileo Galilei is credited with being the first to measure speed by considering the distance covered and the time it takes. Galileo defined speed as the distance covered per unit of time.

## What is meant by uniform speed?

In mathematics and physics, if an object is traveling in such a way that it covers the same distance for each interval of time it is traveling, then it is said to be traveling with uniform speed.

## What speed is 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 is an example of uniform speed?

Example of Uniform Motion: If the speed of a car is 10 m/s, it means that the car covers 10 meters in one second. The speed is constant in every second. Movement of blades of a ceiling fan.

## Can average speed be zero?

Yes, average velocity of a moving body can be zero. Average velocity is displacement by time. So for example, if you are travelling in a circle, and come back to your initial point, displacement is zero.

## What is average speed short answer?

Answer. The total distance travelled by a body in a definite interval of time is known as average speed. mathematically avg. speed = (total distance/total time).

## What is unit of speed?

The speed of an object is how far the object travels in one unit of time. The formula for speed is: speed = distance time. The most common units of speed are metres per second (m/s), kilometres per hour (km/h) and miles per hour (mph).

## How do you get the average speed?

To get average speed, s , divide total distance by elapsed time: Dt. To get elapsed time, t , divide total distance by speed: Ds. To get distance, D , multiply speed times the amount of time: s × t.

## Why is average speed?

The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance. It’s a scalar quantity which means it is defined only by magnitude.
