# Gravitational Field

M: Source of the gravitational field. m: Test mass. g: Gravitational field vector.
Move the test mass (m) around the source (M) to see the strength and direction of M's gravitational field at different positions.

## Test mass

Why does the test mass appear so small compared to the source?
