Thanks for the responses. Good to know I'm not crazy.
In the reference material for the fundamentals of engineering exam, the formula also does not include mass. I guess its a typo. Maybe that's where the author of the presentation got the formula from.
I think it is to differentiate...

I've read that you can view static pressure of a fluid as energy density, which makes sense to me. I've also seen that the power of a fluid flow can be calculated by multiplying the pressure by the volumetric flow rate. However, doesn't a flow also have kinetic energy? How can you calculate the...
I often hear about collisions in terms of impact force. For instance, "the boxer delivered a punch with 100 lbs of force." I have a pair of steel toed shoes that are rated to withstand 70 lbs of force (311 N). But if the shoe experiences an impact instead of being loaded very gradually, wouldn't...
