No. Date Physics " Speed" The time of change position of the object in any direction Is called speed of the object. Speed (v) R Distance travelled (s) Time taken. its SI units is M/S Its Scalar quantity Its dimensional formula. Uniform Speed. IF an object covers equal distance inequal intervals of time. Mon Unform or Varable Speed. 9 IF an object Covers enequal distance In equal intervals of time and Vice: Versa. Average Speed. the ratio of the total distance travelled by the object to the total time taken is called average speed of the object. Average Speed= = Total distance Traveled total time taken.
No. Date IF a havels distance S1. S2. S3 With speeds V1,V2 Vs then Average Speeds S1 V1 V2 V3 t S3 + ) IF particles travels equal distance ( (51=52*S) with velocihes V1 and U2 then Average Speed= = 2v V2 (Vit V2)
