#G FORCE ROLLER COASTER FREE#

An example here is a rocket in free space, in which simple changes in velocity are produced by the engines and produce g-forces on the rocket and passengers. In the absence of gravitational fields, or in directions at right angles to them, proper and coordinate accelerations are the same, and any coordinate acceleration must be produced by a corresponding g-force acceleration. These are examples of coordinate acceleration (a change in velocity) without a sensation of weight. This is demonstrated by the zero g-force conditions inside an elevator falling freely toward the Earth's center (in vacuum), or (to good approximation) conditions inside a spacecraft in Earth orbit. This is also termed 'zero-g', although the more correct term is 'zero g-force'. Objects allowed to free-fall in an inertial trajectory under the influence of gravitation only feel no g-force, a condition known as weightlessness. Stress inside the object is ensured from the fact that the ground contact forces are transmitted only from the point of contact with the ground. (Free fall is the path that the object would follow when falling freely toward the Earth's center). The upward contact force from the ground ensures that an object at rest on the Earth's surface is accelerating relative to the free-fall condition. For example, a force of 1 g on an object sitting on the Earth's surface is caused by the mechanical force exerted in the upward direction by the ground, keeping the object from going into free fall. It is these mechanical forces that actually produce the g-force on a mass. Thus, the standard gravitational force at the Earth's surface produces g-force only indirectly, as a result of resistance to it by mechanical forces. Gravity acting alone does not produce a g-force, even though g-forces are expressed in multiples of the free-fall acceleration of standard gravity. Because of these strains, large g-forces may be destructive. Such forces cause stresses and strains on objects, since they must be transmitted from an object surface. In practice, as noted, these are surface-contact forces between objects.

The g-force experienced by an object is due to the vector sum of all non-gravitational forces acting on an object's freedom to move. Gravitational acceleration (except certain electromagnetic force influences) is the cause of an object's acceleration in relation to free fall. The types of forces involved are transmitted through objects by interior mechanical stresses. When the g-force is produced by the surface of one object being pushed by the surface of another object, the reaction force to this push produces an equal and opposite weight for every unit of each object's mass. Since g-forces indirectly produce weight, any g-force can be described as a 'weight per unit mass' (see the synonym specific weight). The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g (not gram in mass measurement) equal to the conventional value of gravitational acceleration on Earth, g, of about 9.8 m/s 2. Combining this with the vertical g-force in the stationary case using the Pythagorean theorem yields a g-force of 5.4 g.

This is a horizontal acceleration of 5.3 g.

The coaster was originally built with a lift hill until the 2006-2007 refurbishment.This top-fuel dragster can accelerate from zero to 160 kilometres per hour (99 mph) in 0.86 seconds. The drop dives 49 feet (14.9 metres) under the ground into a former mine shaft. It then pushes the car forward into the vertical drop. Tower of Terror lifts the car up with an elevator lift. According to the project manager of the 2006-2007 refurbishment, the ride now has 'drastically lower levels, now reaching close to 4G in the tunnel'. īefore the 2006-2007 refurbishment, this coaster held the record for the highest g-force on a roller coaster at 6.5 G. The ride was designed by Nauta Bussink, manufactured by local companies and built by Gold Reef City. Tower of Terror is a sit-down roller coaster located at Gold Reef City in Gauteng, South Africa.
