Intro Geophysics GRAVITY AND THE FIGURE OF THE EARTH

Intro Geophysics GRAVITY AND THE FIGURE OF THE EARTH. Newton's Law of Universal Gravitation. Consider two point masses, m 1 and m 2 , separated by a distance r. Let r 1 be a unit vector pointing from m 1 to m 2 , then we can write the force F on mass m 2 due to mass m 1 as:.

Oceanic Tides

Oceanic Tides. The Heartbeat of the Ocean. Introduction. Tides are one of the most obvious features of the oceans. Natural rhythms can easily be observed. Long term records of amplitudes and predictions made since 13th century. 1687 Newton applies his law of gravitation to tides.

Spring & neap tides

Spring & neap tides. Tidal range often changes regularly, i.e. every fortnight (14 day period) We see: Spring tides - times of greater tidal range; coincide with full moon or new moon Tidal range during spring tides is usually 20% higher than mean tidal range

Gravity and Motion

Gravity and Motion. What keeps the Earth and moon in orbit?. Gravity. Gravity is a force that attracts objects towards each other The strength of gravity depends on: Mass and Distance . Inertia. Inertia is the tendency of an object to resist a change in motion.
