Скачать или смотреть Newton's Third Law of Motion | Action and Reaction Pairs | JEE NEET Physics

In this video, we explore the fundamental principle of Newton's Third Law of Motion. "For every action, there is an equal and opposite reaction." We clarify common misconceptions about Action-Reaction pairs and discuss how Gravitational Force acts on bodies in different situations.
Concepts Covered on Board:
👉 Newton's Third Law:
Statement: Every action has an equal and opposite reaction.
Key Properties:
Action and Reaction pair always exists.
They act on two different bodies. (This is why they don't cancel each other out to produce zero net force on a single body).
They act simultaneously.
👉 Gravitational Force:
Formula: F = G * m1 * m2 / r^2
Near Earth's surface, this simplifies to Weight: F = mg
Direction: Always directed vertically downwards towards the center of the Earth.
👉 Free Body Diagrams (Weight):
Block on Horizontal Surface: Weight mg acts straight down.
Block on Incline: Weight mg acts straight down (resolved into components mg sin theta and mg cos theta for calculation).
Stacked Blocks: The weight of the upper block pushes down on the lower block.
Curved Surfaces: Weight always points vertically downwards, regardless of surface shape.
