What is the difference between impact score and impact factor, and how do they each measure the influence and significance of research publications?

The impact score is a metric used by funding agencies to evaluate the significance of research proposals, while the impact factor is a metric used to measure the influence of academic journals based on the average number of citations received by articles published in that journal. Both metrics aim to assess the importance and reach of research publications, but they focus on different aspects - impact score on individual research projects and impact factor on journals as a whole.
