Core Concept and Pressure Transmission Definition of Pascal’s Principle: Pressure applied to a confined fluid is transmitted equally and undiminished throughout the fluid and to the container walls. Definition of Pascal’s Principle: Pascal’s Principle says that when you press on a fluid that is trapped in a closed space, the pressure you create is passed … Read more

Core Concept Definition of principle: An object immersed wholly or partially in a fluid experiences an upward buoyant force. Definition of principle: Archimedes’ Principle tells us that when you place an object in a fluid—like water or air—the fluid pushes up on the object. This push is called the buoyant force. The object could be … Read more

Core Concept Definition of principle: As the speed of a fluid increases, the pressure within the fluid decreases, and vice versa. Definition of principle: Bernoulli’s Principle explains what happens to pressure when a fluid like air or water speeds up or slows down. When the fluid moves faster, its pressure becomes lower. When the fluid … Read more

Definition and Formula Definition of atmospheric pressure: It is the force exerted per unit area by the weight of the air above a point on Earth’s surface. Definition of atmospheric pressure: Atmospheric pressure is the force that the air pushes down on a certain area. This happens because the air above us has weight, and … Read more

Definition and Molecular Basis Definition of gas pressure: It is the force per unit area caused by gas molecules colliding with the walls of their container. Definition of gas pressure: Gas pressure is the force that is created when gas molecules move around quickly and hit the walls of the container they are in. These … Read more

Definition and Formula Definition of pressure: Liquid pressure refers to the force applied per unit area within a liquid. Definition of pressure: Liquid pressure is the type of pressure that happens inside a liquid. It refers to how much force is being applied by the liquid on each unit of area. This force comes from … Read more

Definition Elasticity: The ability of a material to return to its original shape and size after a deforming force is removed. Elasticity: Elasticity is the ability of a material or object to return to its original size and shape after a force has stretched or squeezed it. Imagine you are playing with a rubber band: … Read more

Definition Resultant Force: A single vector that represents the combined effect of all individual forces acting on an object. Resultant Force: The resultant force is one overall force that acts on an object, replacing all the smaller individual forces. It tells us what happens to the object as a result of all the forces acting … Read more

Definition and Purpose Definition: Resolution of force is the process of breaking a single force into two or more component forces. Definition: Resolution of force means we take one big force and split it into two smaller forces that are easier to understand. These two smaller forces act in different directions—usually one goes sideways and … Read more

Definition Force Equilibrium: A condition where the net (resultant) force acting on an object is zero, meaning all forces cancel each other out. Force Equilibrium: Force equilibrium is a special condition where all the forces acting on an object cancel each other out completely. This means that the object does not experience any leftover or … Read more
