Newton’s third law quantifies thrust as a reaction force. When a system evacuates or accelerates mass in one direction, the accelerated mass causes an equal magnitude force to be applied in the other direction. If you’ve been swimming, you may feel your weight has decreased. It is because any fluid acts upward on a submerged … Read more
Physics did not necessarily have a father, and no one invented physics either. It was always close by, and as long as humans were curious about the planet, discoveries would be made. That is what scientists do; they find new things. It’s easy to imagine someone thousands of years ago discovering that rapidly rubbing two … Read more
The science of human development seeks to understand the processes that organisms undergo during growth and change. Researchers primarily investigate the following three questions: How do humans develop? What makes humans develop differently from other animals? What are the consequences of individual differences in development, and how can they be maintained or managed? By approaching … Read more
A barometer is a type of scientific equipment used to determine an area’s air pressure. Pressure trends can be used to anticipate short-term weather changes. Numerous air pressure measures are employed in different weather analyses to identify surface trough, differential pressure, and continental borders. Barometers and pressure altimeters (the simplest and most frequent form of … Read more
