Chapter 7: Energy and Power
What you need to learn in this chapter
In this chapter, we will be learning about work, energy, and power. We will define work and learn how to solve problems related to energy in our daily lives. We will also understand the relationship between power and work and solve problems in real-life situations.
Next, we will explore potential energy and kinetic energy. We will learn about gravitational potential energy and how to solve problems using it in our daily lives. We will also calculate elastic potential energy in practical situations.
Lastly, we will study the principle of conservation of energy. We will understand this principle through examples and learn how to solve problems involving the transformation of kinetic energy and potential energy in a closed system.
By the end of this chapter, we will have a solid understanding of work, energy, power, potential energy, kinetic energy, and the principle of conservation of energy.
