I add another panel for put bars about PE,KE,VELOCITY,TIME ETC
And change interface colour make size of window more Small
Have picture post for roller coaster in physic is very good
Explain roller coaster in physic and what happend when access simulation
Will find five tracks RAMP,UP AND DOWN,LOOP,2LOOPS,FIGURE8,CUSTOM
So from this tracks we can control in form o simulation have another window "Panel"
Job of panel shown angle,velocity,potential energy,kinetic energy,total energy,time,etc  Wink  Smiley

What Do Roller Coasters Have To Do With Science and Physics?

Centripetal Force:Centripetal force: the coaster enters a banked curve, and as the track is curved and as the car is in a state of acceleration, it becomes subject to centripetal force, which may give the riders the sensation of being pushed sideways. But if the track is banked at the correct angle for the speed, the force the riders feel push them into their seats. Banking the turn converts the lateral g-forces the riders feel into positive g-forces, as pressure is felt from the floor as well as from the side of the car.

If the speed of the coaster doubles, centripetal forces quadruple, unless the radius of the curve is also quadrupled. As a result, shallower curves are found on larger, faster coasters than on smaller ones. Centrifugal force can be increased by increasing either (1) the speed of rotation, (2) the mass of the body, or (3) the radius, which is the distance of the body from the center of the curve. Increasing either the mass or the radius increases the centrifugal force proportionally, but increasing the speed of rotation increases it in proportion to the square of the speed; that is, an increase in speed of 10 times, say from 10 to 100 revolutions per minute, increases the centrifugal force by a factor of 100. Centrifugal force is expressed as a multiple of g, the symbol for normal gravitational force (strictly speaking, the acceleration due to gravity).

Gravitation:Gravitation, which powers the coaster throughout the entire ride, detaches the car from the lift mechanism and forces it off its highest elevation along the inclined track of the first hill. The potential energy of this mechanical system begins converting into kinetic energy as the coaster reaches a high rate of speed.

Acceleration Force:Acceleration Stress: the coaster approaches the vertical loop, entering at a high rate of speed. Entry may create a heavy force on the riders as high as 5 g, but only for a few seconds--any longer and riders may blackout from acceleration stress. Modern vertical loops are tear-shaped, clothoid loops that have a tighter curve at the top, where the velocity is smaller, than at the exit and entry points at the bottom.
The larger radius at the bottom of the loop reduces centripetal acceleration, thereby lowering the overall g-forces, which naturally increase by 1 g owing to gravitation. Often the designer will adjust the radius at the top of the loop to create a centripetal force of 2 g, allowing the riders, after subtracting the value of gravitation (1 g), to experience normal weight levels while upside down. The queasiness associated with looping rides is owing to some internal organs floating upward, counter to their natural hanging position.

Acceleration:Acceleration: at the bottom of the second hill, the coaster, in theory, reaches an instant of zero acceleration, at the point where its speed is greatest, relative to anywhere else on that hill. Zero acceleration also occurs for an instant at the top of a hill, where in turn the speed is at its lowest level. At the bottom of the dip, the riders experience compression, or acceleration stress, owing to forces greater than their usual weight.

Roller Coaster model explores the relationship between kinetic, potential,
And total energy as a cart travels along a roller coaster.
Users can create their own roller coaster curve and observe the resulting motion.
