What is “Interactions”?
Interactions in Science refer to the relationships among the different forms of matter and the effect they have on each other. Changes as a result of interactions are brought about by the transfer of energy between matter. These may lead to changes in motion, which can be fast or slow as well as changes in conditions, which can be big or small, reversible or irreversible. Such interactions may increase or decrease the stability within a system.
Why is the study of Interactions important?
Why is the study of Interactions important?
Analysis of interactions can reveal patterns in nature that help us to predict how changes in one factor affect other factors in a system or among systems. This knowledge helps us to design solutions and make more informed decisions in our daily lives as there are risks and benefits associated with the applications of Science in society.

● How does knowledge of interactions between and within systems help us better understand and improve our environment?
● What are the examples of interactions between physical phenomena and life processes?
ESSENTIAL TAKEAWAYS
ESSENTIAL TAKEAWAYS
● Interactions usually involve the transfer of energy which can cause changes in motion and/or conditions.
● Our interactions with the world can lead to changes or influence the stability of a system. Thus, we must make responsible choices in our daily lives.
● Our interactions with the environment drive the development of science and technology. At the same time, science and technology influences the way we interact with the environment.
