★☆〖Qบęຮτ ı¨ ø nˇ〗☆★

The speed[v] of an object is defined as the rate of change in its position with respect to the change in time, taking the path of its motion into consideration...

=> The path of its motion is taken into consideration, when it is expressed in terms of the distance travelled by the object...

 \:  \:  \:  \:  \: v =  \frac{s}{t}

=> When it is expressed as the magnitude of the velocity of the object, then it is dependent only upon its initial and final positions...

 \:  \:  \:  \:  \: v  =   |v⃗|  = Limₜ→₀ | \frac{Δr⃗}{Δt}|  =  |\frac{∂r⃗}{∂t} |

=> Speed is always a scalar...

  • SI Unit: metres per second [ms⁻¹]
