Physics is used to describe the physical universe around us, and to predict how it will behave.

Physics is the science concerned with the discovery and characterization of the universal laws which govern matter, movement and forces, and space and time, and other features of the natural world.

Answer 2

Explanation:

Science and engineering are based on measurements and comparisons. Thus, we  need rules about how things are measured and compared, and we need  experiments to establish the units for those measurements and comparisons. One  purpose of physics (and engineering) is to design and conduct those experiments.

For example, physicists strive to develop clocks of extreme accuracy so that any  time or time interval can be precisely determined and compared.You may wonder whether such accuracy is actually needed or worth the effort. Here is one example of the worth: Without clocks of extreme accuracy, the Global Positioning System (GPS) that is now vital to worldwide navigation would be useless.
