- 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
- 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
- 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
- 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
- Average Speed vs. Velocity: Explained - Physics Forums
Though average speed over a finite interval of time is greater or equal to the magnitude of the average velocity, Instantaneous speed at an instant is equal to the magnitude of the instantaneous velocity at that instant Why so?
- 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
