Forces in fluids can be summarized as follows: 1) Newton's laws apply to all forces, including those exerted by fluids like gases and liquids. Gravity and friction are key forces that affect motion in fluids. 2) Pressure in fluids depends on the force applied and the area over which it is applied. It describes how concentrated a force is and can be calculated as force divided by area. 3) Fluids exert buoyant forces on objects within them depending on factors like the object and fluid densities. Bernoulli's principle and Pascal's principle describe how pressure changes within moving fluids.
