Explanation of this video :

In a two-pulley system, Newton's Second Law of Motion (F = ma) helps explain how forces act on masses connected by a string over pulleys. Here’s the breakdown:

Two masses (m₁ and m₂) are connected by a string passing over a pulley.

Forces acting on the system:

The force of gravity on each mass pulls them downward (m₁g and m₂g).
The tension (T) in the string pulls upward on both masses.
Acceleration: Both masses experience the same magnitude of acceleration (a) but in opposite directions due to the string being inextensible.


Solving for acceleration: By combining these equations, you can solve for the acceleration (a) of the system and the tension (T) in the string.

This demonstrates how forces, mass, and acceleration are related in a two-pulley system.
