### Is centripetal acceleration independent of linear acceleration in accelerated circular motion?

Can we say that there is a relationship between them, or are they independent of each other? why? Like does $a_c=v^2/r$ imply $a_c$ and $a_{tangential}$ are related? I am very confused by this ...

### How to draw a velocity curve from Engine power, weight and traction?

Not sure if this is the right forum but I would like to plot a velocity curve of a train, starting at 0km/h and accelerating up to a max speed. The data I have for the locomotive engines are: ...

### How to measure gravitational acceleration in airplane?

I want to see (actually: show to my kids) evidence of the $1/r^2$-decay of gravitational acceleration by measurement, in a way as simple as possible. So I was thinking of measuring gravitational ...

### Is there a relationship between the magnitude of the velocity and acceleration vector?

Given a path, how do the magnitude of the velocity and acceleration vector along the path correlate? I am confused due to the fact that the acceleration is the change of velocity over time and in ...
