Science / Tides and Currents / Equilibrium Tide: Hypothetical tide due to the tide producing forces under the equilibrium theory. Also known as gravitational tide. MORE
Science / Tides and Currents / Tide-Producing Force: That part of the gravitational attraction of the Moon and Sun which is effective in producing the tides on the Earth. The force varies approximately as the mass of the attracting body and inversely as MORE
Science / Tides and Currents / Tide-Producing Potential: Tendency for particles on the Earth to change their positions as a result of the gravitational interactions between the Sun, Moon, and Earth. Although gravitational attraction varies inversely as the MORE
Technology / Motorcycle / G-Force: The amount of gravitational pull simulated during a period of high acceleration or a sudden change in direction. (Plural: G-Forces) MORE
Science / Tides and Currents / Normal Tide: A nontechnical term synonymous with tide; i.e., the rise and fall of the ocean due to the gravitational interactions of the Sun, Moon, and Earth alone. Use of this term is discouraged. MORE
Science / Tides and Currents / Earth Tide: Periodic movement of the Earth's crust caused by gravitational interactions between the Sun, Moon, and Earth. MORE
