Class 11 Physics simulations · Gravitation

Gravity above and below Earth

Move a probe from inside Earth into space and compare the two different gravity laws.

Open the simulation

What to notice

In a uniform-density Earth, gravity rises linearly from zero at the centre to its surface value.

Key relation

Inside: g ∝ r; outside: g ∝ 1/r²

Try this

Compare equal distances above the surface and below it.

What you can change

• Height above surface (depth −): -6000 to 4000 km
