- 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
