## What is distance in physics class 9?

Class 9 : Distance and Displacement – Motion, Class 9, Science | EduRev Notes.

…

Distance : The length of the actual path between the initial and the final position of a moving object in the given time interval is known as the distance travelled by the object..

## What is a formula of mass?

The mass formula is given as. Mass = ρ × v. Where, ρ = density and. v = the volume.

## What is the distance in math?

The distance between two points is the length of a straight line segment that links them. This will also be perpendicular to the line. …

## What is the formula of average distance?

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.

## How do we calculate time?

Here’s how to determine hours worked:Convert all times to 24 hour clock (military time): Convert 8:45 am to 08:45 hours. … Next, Subtract the start time from the end time.Now you have the actual hours and minutes worked for the day.Finally to determined total wage, you will need to convert this to a decimal format.

## What is the distance between two points called?

When unqualified, “the” distance generally means the shortest distance between two points. For example, there are an infinite number of paths between two points on a sphere but, in general, only a single shortest path. The shortest distance between two points is the length of a so-called geodesic between the points.

## What is work formula?

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.

## How do you calculate the distance between two points?

The linear distance between the two points is the square root of the sum of the squared values of the x-axis distance and the y-axis distance. To carry on the example: the distance between (3,2) and (7,8) is sqrt (52), or approximately 7.21 units.

## What is the formula for distance?

To solve for distance use the formula for distance d = st, or distance equals speed times time.

## What is the formula of time?

time = distance ÷ speed.

## What is the distance formula for 3 points?

That is, given P1 = (x1,y1,z1) and P2 = (x2,y2,z2), the distance between P1 and P2 is given by d(P1,P2) = (x2 x1)2 + (y2 y1)2 + (z2 z1)2.

## How do I calculate miles per hour?

Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour.

## What is called average speed?

Average speed is calculated by dividing the total distance that something has traveled by the total amount of time it took it to travel that distance. … Average speed is usually applied to vehicles like cars, trains, and airplanes. It is often measured in miles per hour (mph) or kilometers per hour (kph).

## How do I calculate average speed?

Divide the total distance traveled by the total time spent traveling. This will give you your average speed. . So if Ben traveled 50 mph for 3 hours, 60 mph for 2 hours, and 70 mph for 1 hour, his average speed was about 57 mph.
