What does the term terminal velocity mean?

Terminal velocity is the constant speed (in a particular direction) a body reaches when the forces are balanced , i.e. acceleration = 0 m s -2 . An example of this is a ball bearing dropped in oil. ⬆ Resista...

A car accelerates in 12s from 10m/s to 50m/s. Calculate its acceleration.

Firstly, write down the information you know. S (displacement) - unknown U (inital speed) - 10m/s V (final speed) - 50m/s A (acceleration) - we want to find this out T (time) - 12s The equation that links ac...
