Work is said to be done when the force applied on an object produces a displacement of the object in the direction of force applied. Work = Force x displacement (expression for positive work)
In Class 9 Physics, you will learn about the concept of work. Work is defined as the transfer of energy that occurs when a force is applied to an object and that object is displaced in the direction of the force. Some key points you will cover in Class 9 Physics related to work are:
1. Definition of work.
2. Calculation of work done by a force.
3. Units of work (Joules).
4. Positive and negative work.
5. Work done against gravity.
6. Work done against friction.
7. Work done by a variable force.
8. Work-energy theorem.
These are some of the important topics related to work that you will study in Class 9 Physics.
