Gravity tides and orbits
Cards in this deck (10)
- 1GravityThe force that attracts a body towards the centre of the earth, or towards any other physical body having mass.
- 2Gravitational FieldIn physics, a gravitational field is a model used to explain the influence that a massive body extends into the space around itself, producing a force on another massive body.
- 3MassA large body of matter with no definite shape.
- 4DistanceDistance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is".
- 5OrbitsThe curved path in which a planet, satellite, or spacecraft moves in a circle around another body.
- 6SatellitesA heavenly body that moves around a planet or another larger body.
- 7Solar EclipsesAn eclipse of the sun, when, at a particular observation point, light from the sun is blocked by the interposition of the moon.
- 8Lunar EclipsesThe obscuring of the moon's reflected light by the earth's shadow when the earth passes between the moon and the sun.
- 9TidesThe alternate rising and falling of the sea, usually twice in each lunar day at a particular place, due to the attraction of the moon and sun.
- 10Tidal VariationsThe tidal range is the vertical difference between the high tide and the succeeding low tide. Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth.
