Of course, a horse of ancient times would've been smaller than a large 700kg modern-day riding horse, but nonetheless, we can assume the armoured rider and horse would've weighed well over half a ton and could've reached a speed over 50km/h for a charge... There's quite a bit of force there. :P
The lightest of average cars weighs twice that much and goes much faster. There's no way a knight hits with the force of an automobile.
