it is something you cant see but know and one place where could find it is on a roller-coaster
A roller coaster entering a loop experiences a centripetal force, which is exerted by the track.
When a body is forced to follow a curved path and be directional to the velocity of the path it is known as a centripetal force. Simply put, centripetal force is the cause of circular motion. An example is a loop within a roller coaster that goes upside down, the centripetal force is applied to the track making the coaster travel through at speed.
centrifical force
1. Whirling of a stone tied to a string: The string provides necessary centripetal force for the rotation of stone.2. Turning of vehicles in a circular track: The friction due to the tyres in case of levelled road and the angle of inclination of tracks in case of banked tracks provides the necessary centripetal force.
A loop on a rollercoaster depends how fast you are going and the amount of force pressing down on you. If you're going inside, it feels like you are being pushed into your seat. If you're outside of the loop (Rollercoaster on top of track not bottom) You will feel like you are getting pushed out of your seat. This is called G-Force.
by it being big
Personally a drop.
the name of that roller coaster is called viper. it is located in six flags magic mountain
I think the force of the vehicle [which "holds" it to the track] is called CENTRFUGAL, and the opposite force [provided by the fixed track] is called CENTRIPETAL. Its called centrifical force. Its what keeps the water in a bucket if you swing it around in a circle. Its also what keeps roller coaster riders in their seats when they do loop rides. A centrifuge uses this same force to separate liquids and solids into their layers of density.
Quantum Loop, at Seabreeze Park in NY
Circular loops require greater entry speeds to complete the loop and the greater entry speeds subject passengers to greater centripetal acceleration through the lower half of the loop (greater g-forces). If the radius is reduced at the top of the loop, the centripetal acceleration is increased sufficiently to keep the passengers and the train from slowing too much as they move through the loop. A large radius is kept through the bottom half of the loop, thereby reducing the centripetal acceleration and the g-forces acting on the passengers. Hence, a clothiod Loop. The "Flip-Flap" Railway in 1888 is an example of why circular loops are no longer used in roller coaster designs. The "Flip-Flap" railway subjected passengers to 12G's, 6G's over the maximum g-force modern roller coasters subject their passengers. The high g-forces sustained in a circular loop often resulted in injuries to the neck and back.
the first roller coaster was at connie island but it was a one loop ride. It often caused a harsh whiplash to the rider.
