1If an object is doing a vertical loop, where is reaction force the largest?At the bottom of the loop
2If an object is doing a vertical loop, where is reaction force the smallest?At the top of the loop
3Why is the reaction force larger at the bottom?The reaction force must provide the required centripetal force and support the weight, mg
4Why is the reaction force smaller at the top?The required centripetal force is provided by the reaction force and mg
5Vertical circle diagram: (Note T=R)
6How can we work out the required centripetal force (F) at the top of the loop?F = T3 + mg
7How can we work out the required centripetal force (F) at the bottom of the loop?F = T1 - mg
8If the speed is constant, what else is constant?Force
9What is apparent weightlessness?When contact is just lost / when tension becomes 0
10At the top, what happens when apparent weightlessness occurs?mg = resultant force
m cancels for g=(v^2)/r = 9.81ms^-2
