• It's a set of two equal and opposite forces, but they don't act on the same line.
• No linear acceleration, but they cause rotation (torque).

🌍 Real World Example: Ever tried opening a door by pushing its middle instead of the handle? That's because the handle, being farther from the hinge, provides a more effective torque.

• It's the turning effect due to a couple.
• Torque = Force (F) × Perpendicular distance (d) between the forces.

💡 Fun Fact: Imagine trying to unscrew a bottle cap. If you apply force closer to the edges, it's easier because the perpendicular distance is maximized, creating a bigger torque!

🎡 Wilberforce Pendulum: Ever seen a toy that rotates and then bounces up and down, only to rotate again? That's the pendulum in action. It's a dance between two types of motion!

• The magic spot where it feels like the entire weight of an object is concentrated.
• Force here = straight movement (no rotation).

🌍 Real World Example: Think of a seesaw. The point where it perfectly balances is its center of mass.
