Is velocity ever a scalar quantity? • Physics Forums I thought velocity was always a vector quantity, one with both magnitude and direction When it came to the suvat equations, where v = final velocity, and u = initial velocity, I thought both of those were vector quantities, e g; v (final velocity) 112km hr North u (initial velocity) 0km hr
Calculating Nozzle Flow Rate - Physics Forums Calculating Nozzle Flow Rate To work out the flow rate of water from a nozzle we need to work out the volume in a given period of time To do this we work out the area of the nozzle and then multiply it by the velocity of the water coming from the nozzle to give us volume per unit of time
Relation Between Spring Constant and Angular Velocity I was going through Periodic Motion chapter of my book and came across an equation while defining the relation between Time Period of on oscillating particle and force constant k m=w2 which was applied in, T = 2xpie angular velocity can anyone please help me define this equation I can't seem
Exit velocity of a gas through a hole - Physics Forums Hello, Given: A large pressurized container with a small hole in a side The sides of the container are VERY thin such that the thickness of the sides can be ignored The pressure difference between the container and the environment is not large enough to result in choked flow The outflow
Can you have a negative average velocity? • Physics Forums I understand that it's possible to have a negative instantaneous velocity, but I'm wondering if it's possible to have an negative average velocity For example, let's say you start heading north at a constant 10 mph for an hour The second hour, you drive south (directly toward the starting
