- 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 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
- 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?
- 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

- Torque Power: Understanding Angular Velocity - Physics Forums
how can we say that torque is equal to power angular velocity though we know that torque is equl to I x (change of angular velocity over time ) and how can we relate torque to (angular velocity) , as we know that a rotating gear at constant angular velocity has no torque on it or bettter
- 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
