Physical science is the study of physics and chemistry of nature. From the materialist and functionalist viewpoints it overlaps the life sciences where ecology studies the evidences of historical facts or evolution. Physics along with Mathematics and Chemistry is one of the fundamental sciences because the other natural sciences like biology, geology etc., deal with systems that seem to obey the laws of physics. According to Physics, the physical laws of matter, energy and the fundamental forces of nature govern the interactions between particles and physical entities (such as planets, molecules, atoms or the subatomic particles). Some of the basic pursuits of physics are describing the nature, measuring and quantifying of bodies and their motion, dynamics and so on. But what I want to touch up on is mass, force and weight. Considering that I am a Construction Management major, I believe these are the top key physics implemented in the pursuit of construction. Mass is a measure of the amount of material in an object, weight is the gravitational force acting on a body (although for trading purposes it is taken to mean the same as mass), force is a measure of the interaction between bodies and load usually means the force exerted on a surface or body.
Mass is a measure of the amount of material in an object, being directly related to the number and type of atoms present in the object. Mass does not change with a body's position, movement or alteration of its shape unless material is added or removed. The unit of mass in the SI system is the kilogram (kg). Mass can also be defined as the momentum of resistance to acceleration.
In the trading of goods, weight is taken to mean the same as mass, and is measured in kilograms. Scientifically, however, it is normal to state that the weight of a body is the gravitational force acting on
