Newton’s Third Law

📖 Official statement:

“For every action, there is an equal and opposite reaction.”


🧠 What it really means:

If you push something, it pushes back just as hard — at the same time, in the opposite direction.


💥 Real-world examples:

Action

Reaction

You jump off the ground

Ground pushes you upward

Balloon lets air out

Air goes one way → balloon flies opposite

You punch a wall (ouch)

Wall punches your fist back (same force!)

Rocket pushes exhaust down

Exhaust pushes rocket up


🔄 Key Points:

  1. Equal in strength
    → Both forces are the same size.

  2. Opposite in direction
    → If you push left, the reaction is right.

  3. Happen at the same time
    → No delay. Instantly. Always paired.


🔑 Important truths:

  • These forces act on different objects, not the same one.

  • That’s why they don’t cancel out.

Example: You push a wall. Wall pushes you back. Two different forces on two different things.


🔥 Real talk:

If you feel resistance, it means you’re already applying a force — and the world is pushing back equally. That’s why you don’t move walls, and why they hurt when you try.


🧠 Masterline:

“You can’t touch without being touched back.”
