The wooden ball floats in the water, about half immersed in it. What are the main forces acting on the ball?

Two main forces act on a ball floating on the surface of the water.

The first force – the force of gravity – acts on all objects with mass. Gravity, or weight, arises from gravity. It is calculated by the formula F = m × g, where g is the gravitational acceleration or gravitational constant, on Earth equal to approximately 9.8 m / s2 (10 N / kg is also used).

The second force – the force of Archimedes – arises from the fact that a ball immersed in water pushes out part of the liquid. The buoyancy force is equal to the weight of the pushed volume of water and is calculated by the formula F = ρ × g × V.

Since the ball is on the surface, the force of gravity is less than the force of Archimedes.
