  2. Archimedes' principle - Wikipedia

    en.wikipedia.org/wiki/Archimedes'_principle

    An object whose weight exceeds its buoyancy tends to sink. Calculation of the upwards force on a submerged object during its accelerating period cannot be done by the Archimedes principle alone; it is necessary to consider dynamics of an object involving buoyancy. Once it fully sinks to the floor of the fluid or rises to the surface and settles ...

    An object whose weight exceeds its buoyancy tends to sink.

  4. Physical coefficient - Wikipedia

    en.wikipedia.org/wiki/Physical_coefficient

    To find the coefficient of a chemical compound, you must balance the elements involved in it. For example, water: H 2 O. It just so happens that hydrogen (H) and oxygen (O) are both diatomic molecules, thus we have H 2 and O 2. To form water, one of the O atoms breaks off from the O 2 molecule and react with the H 2 compound to form H 2 O. But ...

  5. Cartesian diver - Wikipedia

    en.wikipedia.org/wiki/Cartesian_diver

    A Cartesian diver or Cartesian devil is a classic science experiment which demonstrates the principle of buoyancy (Archimedes' principle) and the ideal gas law.The first written description of this device is provided by Raffaello Magiotti, in his book Renitenza certissima dell'acqua alla compressione (Very firm resistance of water to compression) published in 1648.

  6. Submerged specific gravity - Wikipedia

    en.wikipedia.org/wiki/Submerged_specific_gravity

    Submerged specific gravity is a dimensionless measure of an object's buoyancy when immersed in a fluid.It can be expressed in terms of the equation = where stands for "submerged specific gravity", is the density of the object, and is the density of the fluid.

  7. Displacement (fluid) - Wikipedia

    en.wikipedia.org/wiki/Displacement_(fluid)

    Measurement of volume by displacement, (a) before and (b) after an object has been submerged. The amount by which the liquid rises in the cylinder (∆V) is equal to the volume of the object. In fluid mechanics, displacement occurs when an object is largely immersed in a fluid, pushing it out of the way and taking its place. The volume of the ...

  8. Orders of magnitude (force) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(force)

    One kilogram-force, nominal weight of a 1 kg (2.2 lb) object at sea level on Earth [15] 10 N 50 N Average force to break the shell of a chicken egg from a young hen [16] 10 2 N 720 N Average force of human bite, measured at molars [17] 10 3 N kilonewton (kN) 5 kN The force applied by the engine of a small car during peak acceleration [citation ...

  9. Bouncing ball - Wikipedia

    en.wikipedia.org/wiki/Bouncing_ball

    The lift coefficient is a complex factor which depends amongst other things on the ratio rω/v, the Reynolds number, and surface roughness. [12] In certain conditions, the lift coefficient can even be negative, changing the direction of the Magnus force (reverse Magnus effect). [4] [13] [14]
