Elasticity, fluid pressure, and structural properties.
Matter exhibits unique properties when subjected to forces. Solids stretch and compress elastically, while fluids transmit pressure and exert buoyant forces.
This unit covers solid elasticity (Hooke's Law, Young's Modulus), hydrostatic fluid pressure, and Archimedes' Principle of buoyancy.
Elasticity is the property of a body to regain its original shape after deforming forces are removed.
•Hooke's Law: F = -k * x, where k is the spring constant.
•Elastic limit is the threshold beyond which permanent deformation occurs.
Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced.
•F_buoy = ρ_fluid * V_submerged * g.
•An object floats if its density is less than the fluid's density.
The restoring force (F) exerted by a spring is proportional to the displacement extension (x) from equilibrium.
Stiffness of a material, calculated as tensile stress (F/A) divided by tensile strain (ΔL/L0).
The gauge pressure (P) at depth h in a fluid of density ρ.

Step-by-step Solution:
An iron nail sinks because its density is much higher than water. An iron ship floats because it is hollow; its large volume displaces a massive amount of water, making the average density of the ship (iron + air inside) much lower than the density of water.
