Velocity Systems Hybrid

velocity systems hybrid represents a topic that has garnered significant attention and interest. Is velocity ever a scalar quantity? 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... Phase and group velocity for the wave function - Physics Forums.

As far as I know, if we have a wave function as a sum of many momentum eigen function, i.e., ##\psi=\sum_k \alpha_k e^ {i (kx-\omega t)}##, the group velocity is the velocity of the whole wave function while phase velocity is the velocity of the individual components. Understanding Zero Velocity and Non-Zero Acceleration: Explained. I heard it would be possible to have zero velocity & non zero acceleration (I know the opposite situation where there is velocity (constant), but zero...

How Long Does It Take a Person to Reach Terminal Velocity?. The terminal velocity will depend very much on how this person falls, how much of his body is exposed to the air resistance. Furthermore, think of someone falling foot down making a straight vertical line, this person would experience much less air resistance than someone falling face flat towards the ground, sprawled out.

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. It's important to note that, 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.

Stationary object, constant velocity? The discussion centers on the concept of velocity in relation to stationary objects, with one participant arguing that a stationary object can be said to have a constant velocity of zero, while the other contends that velocity, being a vector, cannot be attributed to an object with an undefined direction. Another key aspect involves, the debate touches on the distinction between velocity as a vector and speed as a scalar ... How to find the initial velocity given only angle and distance traveled.

Homework Statement An object is shot (from a cannon) at an angle of 33 degrees and landed 85 m away. Calculate the magnitude of the initial velocity (Hint:Look at the x direction and solve for Vox) Homework Equations Other questions I must answer. If you have time, help with these would... Finding the velocity at the top of a loop • Physics Forums.

I've been spending the last 1½ week trying to figure this out on my own, but I just can't find the answer. A car (toy car) weights at about 0,062 Kg, and enters the loop at the speed of 0,60 m/s. The radius of the loop is 0,2011 m. Find the speed at the top of the loop (Not... Exit velocity of a gas through a hole • Physics Forums.

The discussion centers on the relationship between the exit velocity of gas and the diameter of a hole in a pressurized container. Initially, it was suggested that the exit velocity increases with larger hole diameters based on Bernoulli's principle and the continuity equation. It's important to note that, however, further analysis revealed that the exit velocity is primarily determined by the pressure difference between ...
