Every object gets attracted towards the earth. The force with which the earth attracts everything towards itself is called the gravitational force of earth. Newton’s 1st law of motion - An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force . Law of inertia - A body will preserve its velocity and direction so long as no force in its motion's direction acts on it. Buoyant force - B uoyancy refers to a force that arises from the pressure exerted on an object by a fluid (a liquid or a gas). Since it's a force, we call it the buoyant force.
