P4_7 Greatest Gravity

Magdalena Szczykulska, Jason Watson, Lilian Garratt-Smithson, Alistair William Muir


Earth is not of uniform density, but consists of many layers, causing acceleration due to free fall to be a non-linear function of radius. A model is constructed to evaluate at which radius the greatest gravitational acceleration is felt. This point was found to be at the meeting point of the lower mantle and the outer core, where the acceleration peaks at a = 10.8 ms-2.
