gravitation

  

      n  
1    the force of attraction that bodies exert on one another as a result of their mass  
2    any process or result caused by this interaction, such as the fall of a body to the surface of the earth,   (Also called)    gravity             See also       Newton's law of gravitation  
  gravitational      adj  
  gravitationally      adv  


API gravity scale  
      n   the American Petroleum Institute gravity scale: a universally accepted scale of the relative density of fluids that is used in fuel technology and is measured in degrees API. One degree API is equal to (141.5/d)--13.5, where d = relative density at 288.7K  
   See also       Baumé scale  
centre of gravity  
      n   the point through which the resultant of the gravitational forces on a body always acts  
gravity  
      n   pl   , -ties  
1    the force of attraction that moves or tends to move bodies towards the centre of a celestial body, such as the earth or moon  
2    the property of being heavy or having weight  
   See also       specific gravity       centre of gravity  
3       another name for       gravitation  
4    seriousness or importance, esp. as a consequence of an action or opinion  
5    manner or conduct that is solemn or dignified  
6    lowness in pitch  
7    modifier   of or relating to gravity or gravitation or their effects  
gravity wave, gravity feed     
     (C16: from Latin gravitas weight, from gravis heavy)  
gravity cell  
      n   an electrolytic cell in which the electrodes lie in two different electrolytes, which are separated into two layers by the difference in their relative densities  
gravity dam  
      n   a dam whose weight alone is great enough to prevent it from tipping over  
gravity fault  
      n   a fault in which the rocks on the upper side of an inclined fault plane have been displaced downwards; normal fault  
gravity platform  
      n   (in the oil industry) a drilling platform that rests directly on the sea bed and is kept in position by its own weight; it is usually made of reinforced concrete  
gravity scale  
      n      See       API gravity scale  
gravity wave  
      n     (Physics)  
1    a wave propagated in a gravitational field, predicted to occur as a result of an accelerating mass  
2    a surface wave on water or other liquid propagated because of the weight of liquid in the crests,   (Also called)    gravitational wave  
quantum gravity  
      n     (Physics)   a theory of the gravitational interaction that involves quantum mechanics to explain the force  
specific gravity  
      n   the ratio of the density of a substance to that of water  
   See       relative density  
zero gravity  
      n   the state or condition of weightlessness
