is rain drop falling a contact force or a Non contact force

1 answer

A raindrop falling is primarily affected by gravity, which is a non-contact force. Gravity pulls the raindrop towards the Earth without any contact between the raindrop and the Earth itself. However, when the raindrop reaches the ground (or any other surface), it experiences contact forces upon impact. So, while the forces acting on a falling raindrop as it descends (like gravity) are non-contact forces, the interaction with the ground involves contact forces.
