Density is a fundamental dimension
WebThe fundamental factor that affects an object’s buoyancy is its density in relation to the medium it is placed in. If the object is denser than the fluid medium, it will sink; if it is less dense, it will float. For example, consider a metal block and a plastic ball of the same size placed in a shallow pool of water. WebPhysicists often use square brackets around the symbol for a physical quantity to represent the dimensions of that quantity. For example, if r r is the radius of a cylinder and h h is its height, then we write [r] = L [r] = L and [h] = L [h] = L to indicate the dimensions of the radius and height are both those of length, or L. Similarly, if we use the symbol A A for …
