Pressure forces refer to the forces exerted on an object due to the pressure of a fluid (liquid or gas) acting on it. These forces can cause objects to move, change shape, or experience deformation.
Imagine you are standing in a crowded subway train. As more people enter the train and the space becomes tighter, you feel a force pushing against your body from all directions. This force is similar to pressure forces acting on an object.
Buoyant Force: The upward force exerted by a fluid on an object immersed in it, which opposes the weight of the object.
Pascal's Principle: The principle that states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the fluid.
Bernoulli's Principle: The principle that states that as the speed of a fluid increases, its pressure decreases, and vice versa.
