The normal component of acceleration is known as the "centripetal" component ... there is a 90 degree angle between velocity and acceleration. On the right side, P moves with increasing/decreasing ...

Answer: the critical speed occurs when the acceleration of the water due to gravity equals the centripetal acceleration, that is when g equals velocity squared divided by radius. This clip will be ...

Since energy is conserved (the gravitational force is conservative), we can use the work/energy equation ... green velocity vector is shown along with the acceleration in terms of its tangential and ...
