Lab 1: Density and Hooke’s Law Introduction Part 1: Density Density is the property of how much matter is in one body mass. It is given by the equation ρ = M V , where rho ( ρ ) is the unit for density of an object, M is the mass of the object, and V is the volume of the object. Every material has its own density, and the same body can have a different density at different times, such as when temperature and pressure are changed and a new volume is calculated from it. The specific material we measured was aluminum, which has a density of 2.70 g/mL (Haliday, et al). The volume of a cylinder is given by the equation of V=πr 2 h , where r is the radius of the cylinder and h is the height of said cylinder. Part 2: Hooke’s Law Hooke’s Law states that force acting on a spring is proportional to the extension of the spring and its own natural “springiness”. The equation for this force is given by F=-kx , where F is the force exerted on the spring, k is the spring constant (its “springiness”), and
