* Quantitative Measurements: Physics relies heavily on precise measurements and mathematical descriptions of phenomena. This allows for highly accurate predictions and explanations of natural events.

* Fundamental Laws: Physics seeks to identify universal laws that govern the behavior of matter and energy. These laws are based on rigorous experimentation and mathematical reasoning, leading to a high degree of certainty.

* Objective Reality: Physics aims to describe the physical world objectively, independent of human perception or interpretation. This objectivity contributes to the reliability and repeatability of its findings.

* Predictive Power: The laws of physics allow for accurate predictions of future events, such as the trajectory of a projectile or the behavior of a celestial body. This predictive power is crucial for engineering, technology, and other scientific fields.

However, it's important to note that even physics is not entirely "exact":

* Quantum Mechanics: The realm of quantum mechanics introduces inherent uncertainty and randomness, challenging the notion of a purely deterministic universe.

* Limited Understanding: While physics has made remarkable progress, there are still many unsolved mysteries and limitations to our understanding of the universe, such as dark matter and dark energy.

* Assumptions and Approximations: Many physical models rely on simplifying assumptions and approximations. While these can be very useful, they also introduce a degree of uncertainty.

Therefore, calling physics the "exact science" is an oversimplification. While it strives for accuracy and precision, it is ultimately a human endeavor that is constantly evolving and refining our understanding of the universe.
