The terms work, energy, and power are common words in English. In physics we require precise definitions so that these terms can be formulated mathematically. Readers will find that definitions in physics do not always match the usage of the words. For example, although a student may do homew...
This chapter will teach us about concepts like work, energy and power. Work, energy and power are essential concepts in physics. Work is the displacement of an object caused by a force (push or pull). Energy is defined as the ability to perform work. We also get to know about the work...
