It is a formula of which formulae is its plural.
The term that springs to mind is LAW.
It is formula of which the plural is formulae
The term you are looking for is "physical equations." These equations describe the relationships between quantities in the physical world, often derived from fundamental principles of physics.
The equations of motions.
Scientific Law.
work = force x distance time = distance : time power = work : time force = ?
It could be termed a "law".
Scientific laws. Scientific laws. Scientific laws. Scientific laws.
A physical model is a representation of a system using physical components, while a mathematical model is a representation using mathematical equations. Physical models are tangible and can be observed, while mathematical models rely on calculations and assumptions based on mathematical principles. Both types of models serve to simulate and understand real-world phenomena.
I'm guessing that you're talking about a Law of Physics. Laws are typically described using mathematical equations. Like newton's second law: F=ma (force=mass*acceleration) Theories, on the other hand are usually just a description or explanation of behavior, like how light can behave like a wave and a particle.
Mathematical sciences are a wide array of sciences that are based on mathematical principles.
