Circular Motion and Gravitation Review

A 535-kg rider on a roller coaster car is moving 103 m/s at the top of a loop which has a radius of curvature of 729 m Determine the normal force experienced by the rider Answer 254 N At the top of the loop, both the gravitational and the normal force are directed inwards as shown in the free-body diagram at the right...

Vertical Circles

Top of a Hill The only forces acting on the rider are the upward normal force n exerted by the car and the downward force of gravity w, the rider s weightThese add together, as vectors, to provide the net force F net which is the centripetal force F c, directed toward the center of the circle The normal force may also be called the rider s apparent weight for this is the force of the seat ....

Roller Coaster Physics

The kinetic energy of the roller coaster is where v is the speed of the roller coaster If we assume no friction losses, then energy is conserved Therefore, Thus, mass cancels out, and This result is nice because it allows us to approximate the speed of the roller coaster knowing only the vertical height h that it fell on any part of the track...
