Mechanical energy is the sum of Kinetic Energy and Potential Energy. A. Kinetic Energy (KE) The energy possessed by an object due to its motion. = mass of the object = velocity of the object B. Potential Energy (PE)
Work, Energy, and Power are fundamental concepts in Physics that explain how the universe functions. For Class 9 students, mastering these topics is crucial for scoring well in exams and building a strong foundation for higher secondary education. work energy and power class 9 notes pdf download
The energy possessed by an object due to its position or configuration. Mechanical energy is the sum of Kinetic Energy
In Physics, work is said to be done only when a force applied to an object causes it to move (displace) in the direction of the force. = mass of the object = velocity of the object B
Energy is the capacity or ability to do work. Without energy, work cannot be performed. Joule (J).
