sir si unit of distance is (m) not (m/s) 5:08

[vanssgamerz]

The speed of a body is the rate of change of distance with time. Numerically it is the distance travelled by the body in 1 second. It is scalar quantity .. SI unit of speed is metre per second (m s–¹) and it's CGS unit is centimeter per second (CM s–¹)

Sir displacement be negative or positive or 0 also

[vanssgamerz]

Instantaneous speed: when the speed keeps on changing, it's speed at any instant is measured by finding the ratio of the distance travelled in a very short time interval to the time interval . This speed is called the instantaneous speed. The speedometer measured the instantaneous speed

[vanssgamerz]

Average sppedd-- the ratio of the total distance travelled by the body to the total time journey iss called it's average speed.
In case of body moving with uniform speed the instantaneous speed and the average speed are equal

5:14 the is unit of distance will be metre(m) and not m/sec Pls note the error

sir please keep making videos i need it i am in 9th. And also thank you sir🙏🏽🙏🏽

[piyushkumargupta]

But I can't see your video because I can't purchase you package

Uniform speed ---- A body is said to be moving with uniform speed if it covers equal distances in equal intervals of Time throughout it's motion. Eg. The motion of a ball on a frictionless plane esurfacce is with uniform speed.
Knowing the uniform speed of a body, we can calculate the distance moved by the body in certain interval of time. If aa body move with a uniform speed v, the distance travelled by it in time t is given as : S= vt

Sir S.I. unit of distance metre per second Kab Se Hone Laga

[AyushSharma-fbqg]

5 saal se displacement ki definition padh raha hoon aaj tak kabhi bhi displacement k bare mein samaj nahi aya. Exam mein rat kar likhke aa jata hu. Aaj pata chal gaya ki displacement ka matlab kya hota hai.

Thankyou so much sir, your explanation really helps me a lot for my exams because on online classes somethimes their were a lot of network issues on my teacher place so I wasn't able to understand something but you have really explained me very well ty so much sir I'm grateful to you 🙏

[SChandtgtNM]

Unit of distance is metre not m/sec sir.

[amaangaming]

Sir in 4.52sec.According to Pythagoras theorem the length of BA is 5cm.

[vanssgamerz]

Non uniform or variable speed-- A body is said to be moving with a non uniform speed if it covers unequal distances in equal intervals of time. Eg. The motion of a ball on a rough surface, the motion of car in crowded street.
In case of bodies moving with non uniform speed, we specify their instantaneous speed and the average speed.

Sir we can't afford membership . Please help us

[fizzdignity]

5:10 the si unit of distance in not m/s, it is meter

[regulartwelthie]

Such a nice explaination...better than my tutor🔥😀👍👍👍
