The physics of movement: how your muscles calculate torque
In short: Ever wonder how your body manages to lift heavy objects without collapsing? This video breaks down the physics of moments—the turning effects of force—and explains how your muscles use balanced equations to move your world.
A moment is defined as the rotational or turning effect produced by a force. To create this effect, a force must act upon a pivot point. These moments are categorized as either clockwise or anticlockwise depending on the direction of the turn.
The video demonstrates the mathematical formula for calculating these effects: Moment = Force x Perpendicular Distance (M = F x d). By understanding these principles, you can calculate the specific muscle force required to keep an object stationary, based on the rule that total anticlockwise moments must equal total clockwise moments.
