- 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
- 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 acceleration) Could anyone please give me a clue on this? Thanks in advance
- 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
- Velocity of air coming out of a nozzle - Physics Forums
If the pressure on one side of the orifice is constant and less than the critical choke pressure, then that should be the velocity If the pressure is coming from an air tank of finite volume, this velocity is just a snapshot in time The pressure, and therefore velocity, will decrease over time
- Addition of Velocities (Velocity Composition) in Special Relativity
The “Addition of Velocities” formula (more correctly, the “Composition of Velocities” formula) in Special Relativity v A C c = v A B c + v B C c 1 + v A B c v B C c is a non-intuitive result that arises from a “hyperbolic-tangent of a sum”-identity in Minkowski spacetime geometry, with its use of hyperbolic trigonometry However, I claim it is difficult to obtain this by looking at
- 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
- How to find angular velocity from torque? • Physics Forums
Hello, If I apply force on a rigid cube, I can find the torque τ as: τ = F x r Now, from torque τ I can know about the axis of rotation but how much should I rotate the cube How can I find the angular velocity ω from torque τ? Or is there any other way by which I can find how much the
- 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
