The centripetal component of acceleration ALWAYS points toward ... On the left side, P is traveling with a constant speed; as discussed above, there is a 90 degree angle between velocity and ...

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 ...

Gravitational attraction provides the centripetal force needed to keep ... in a circular orbit at a constant speed has a changing velocity. This is because velocity is a vector quantity that ...
