What does G-Force feel like roller coaster?
What does G-Force feel like roller coaster? No matter how far the drop, a roller coaster will only subject the rider to weightlessness (what you call the “dropping feeling”). It won't actually throw the rider upward against the seat restraints with force, which is like pulling positive gs upside down.
How many Gs are fatal?
Changes in speed are expressed in multiples of gravitational acceleration, or 'G'. Most of us can withstand up to 4-6G. Fighter pilots can manage up to about 9G for a second or two. But sustained G-forces of even 6G would be fatal.
Where do you feel heaviest on a roller coaster?
Riders may experience weightlessness at the tops of hills (negative g-forces) and feel heavy at the bottoms of hills (positive g-forces). This feeling is caused by the change in direction of the roller coaster. At the top of a roller coaster, the car goes from moving upward to flat to moving downward.
