Описание: Lec 07 | Unit 03 | Dynamics | Class 9 Physics | ZS Sciences
In this lecture, we clearly explain the difference between force and weight according to the Class 9 Physics syllabus. Students often get confused between these two important concepts of Dynamics, but in this video, everything is explained in a simple, conceptual, and step-by-step method.
🔹 What is Force?
Force is a push or pull that can change the shape, direction, or state of motion of a body. It is a vector quantity and is measured in Newton (N).
🔹 What is Weight?
Weight is a specific type of force. It is the force of gravity acting on a body.
Weight = m × g
It also has direction (towards the center of the Earth).
