Awesome Formula Of Velocity In Physics Class 9
Velocity Formulas and SI unit also available.
Formula of velocity in physics class 9. Speed and velocity can be a little confusing for most of us. 1 In travelling from Pune to Nagpur Rahul drove his bike for 2 hours at 60 kmph and 3 hours at 70 kmph. Now let us look at some of the examples to understand this concept easily.
Now recall the formula which is velocity displacement time. Time in seconds time in minutes number of seconds in a minute. So both are not equal.
It is a vector quantity so it has both magnitude and direction. Velocity DisplacementTime 40 - 401 01 0. Class 9 Physics Formula and Important terms CBSE Class 9 Physics Summary.
V a t. In general average speed formula is. U2 v2 2as.
It is a vector quantity. A train accelerates from 36 kmh to 54 kmh in 10 sec. A car is moving with an initial velocity of 30 ms and it touches its destiny at 80 ms.
Average velocity V av 30 802. 7 velocity It is t he rate of change of displacement of a body with the passage of time. Well the difference between speed and velocity is that speed gives us an idea of how fast an object is moving whereas velocity not only tells us its speed but also tells us the direction the body is moving in.
