Terminal velocity experiment (PAG 1.2)

If u want to understand how can the velocity of the falling ballbearing can be taken to Terminal Velocity

One is equation approach_ other is empirical

# a differential equation

Like we have in damped oscillation... it will show that the velocity gets "damped" fairly quickly

#If u see this video 👆🏽- he clarifies that the time taken to cover all distances would be same

Again implying thereby terminal velocity is reached very quickly
