1
Q
radial acceleration
A
acceleration towards the centre
v²/r
or r(dθ/dt)²
2
Q
tension in vertical circle
A
to complete full circles the tension in the string must be greater than or = 0 at the highest point of the vertical circular orbit
3
Q
speed in vertical circle with rods
A
the speed must be greater than zero at the highest point
4
Q
tangential acceleration
A
dv/dt = r d²θ/dt²
5
