distance formula physics class 9

Determine the acceleration of the scooter and the distance travelled. The physics formulas for class 9 are given here to guide students to understand the concepts effectively. Distance is the total movement of an object without any regard to direction. \(Speed = \frac{Distance}{Time}\) Dimensional formula of Distance = M 0 L 1 T 0 Dimensional formula of time = M 0 L 0 T 1 Dividing the dimensional formula of distance by the dimensional formula of time, we get: \(\frac{M^0L^1T^0}{M^0L^0T^1}=M^0L^0T^{-1}\) Therefore, the dimensional formula of speed = M 0 L 1 T-1. view more.
