Moving an object up an inclined plane requires less force than lifting it straight up, at a cost of an increase in the distance moved. [4] The mechanical advantage of an inclined plane, the factor by which the force is reduced, is equal to the ratio of the length of the sloped surface to the height it spans.
Moving walkway inside the Changi Airport station of the Singapore MRT. A moving walkway, also known as an autowalk, [1] moving pavement, [2] moving sidewalk, [3] travolator, [4] or travelator (British English), [5] is a slow-moving conveyor mechanism that transports people across a horizontal or inclined plane over a short to medium distance.

But Pluto has in many ways only grown in astronomers’ estimations. It is now known to be part of an entire system of objects, gravitationally anchoring a cluster of five moons; it has a surface ...
The displacement of rocks with respect to the surface is called exhumation. This simple equation relates the three kinds of displacement: Surface uplift = uplift of rock – exhumation. The term geoid is used above to mean mean sea level and makes a good frame of reference. A given displacement within this frame of reference allows one to ...
The Mystery Spot is a tourist attraction near Santa Cruz, California, opened in 1939 by George Prather. [2] Visitors experience demonstrations that appear to defy gravity, on the short but steep uphill walk and inside a wooden building on the site.
Amateur archaeologists in England have unearthed one of the largest Roman dodecahedrons ever found, but mystery surrounds what it was actually used for. The 12-sided object is one of just 33 known ...
Tumblehome or tumble home is the narrowing of a hull above the waterline, giving less beam at the level of the main deck. The opposite of tumblehome is flare . A small amount of tumblehome is normal in many naval architecture designs in order to allow any small projections at deck level to clear wharves .
The Magnus effect is a phenomenon that occurs when a spinning object is moving through a fluid or gas (air). A lift force acts on the spinning object and its path may be deflected in a manner not present when it is not spinning. The strength and direction of the Magnus effect is dependent on the speed and direction of the rotation of the object ...
