A zero-g roll on The Incredible Hulk. A zero-g roll or zero-gravity roll is a roller coaster inversion where the track twists 360 degrees as it rises and falls in elevation, usually at the crest of a hill. The element gets its name from the weightless effect of zero g-force that a rider experiences during the inversion. [50] [51] [52]
Weightlessness is the complete or near-complete absence of the sensation of weight, i.e., zero apparent weight. It is also termed zero g-force, or zero-g (named after the g-force) [ 1 ] or, incorrectly, zero gravity. Microgravity environment is more or less synonymous in its effects, with the recognition that g-forces are never exactly zero.
Zero Gravity Corporation (also known as Zero-G) is an American company based in Exploration Park, Florida, formerly of Fort Lauderdale, Florida, which operates weightless flights from United States airports. Zero-G is governed under Part 121 of FAA regulations (as are all US commercial passenger and cargo airlines) enabling the company to cater ...
Key: N = Normal force that is perpendicular to the plane, W=mg, where m = mass, g = gravity, and θ = Angle of inclination of the plane. The mechanical advantage of an inclined plane is the ratio of the weight of the load on the ramp to the force required to pull it up the ramp. If energy is not dissipated or stored in the movement of the load ...
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, [a] motorway, [b] and expressway. [c] Other similar terms include throughway or thruway[d] and parkway.
Block on a ramp and corresponding free body diagram of the block. In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the ...

The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform. It is so named based on its resemblance to the teeth of a plain-toothed saw with a zero rake angle. A single sawtooth, or an intermittently triggered sawtooth, is called a ramp waveform. The convention is that a sawtooth wave ramps upward and then sharply drops.
