Hi list,
Asking this question with no shame ^^;
This might be basic, but what is the difference between a force and a
velocity ?
Sorry for being half brained...
They are completely different concepts, in short:
Force = mass * acceleration
Acceleration = Velocity / time
Velocity = distance-traveled / time
Actually speed = distance-traveled/time, velocity is more like position /
time (it's a vector).

It's actually incorrect more so than clear.
Distance traveled divided by time is not velocity. It's speed, a scalar
value.
Velocity has to do with the rate of change and is represented by a vector
providing direction, and it's magnitude representing speed. So while speed
is the simple speed an ob
Reading that after sending it (when else would one proof read?) I realize
it might come across as a bit aggressive with the opening comment.
My apologies to César if that's the case, it sure wasn't intended to be or

Velocity is the speed and direction at which an object moves.
Force is something with a strength and a direction that causes acceleration
on the object and has an effect on its velocity.

You have some object, that is flying through space with a VELOCITY.
Maybe it is fly
Apologies, there are a couple of number typos in the first one.

I'm a big fan of sticking to definitions, but they normally need to be
presented in sets to the uninitiated, or they become confusing.
IE: if you decide to put forward an example sampled across 6.6 seconds

i have no problem with the definitions and i just thought you might
