  • black hole

    Black holes are areas in space, where gravity is so strong that nothing, not even light, can escape from them. Black holes are thought to be formed by collapsed stars.

  • center of gravity

    The center of gravity of an object is a point in it. If this point is above the base of the object, it stays stable, rather than falling over.

  • gravitational redshift

    (in general relativity) the shift toward longer wavelengths of electromagnetic radiation emitted by a source in a gravitational field, especially at the surface of a massive star.

  • gravity assist

    the technique of using the energy of a gravitational field and the orbital velocity of a planet to change the speed and trajectory of a spacecraft.

  • tidal force

    the gravitational pull exerted by a celestial body that raises the tides on another body within the gravitational field, dependent on the varying distance between the bodies.

  • acceleration of gravity

    the gravitational acceleration of a freely falling object, expressed in terms of the rate of increase of velocity per second: on earth 980.665 cm (32.17 ft) per second per second is the standard
