>Physics is based on metaphor not math. We take common experiences like space, distance, speed, temperature, "energy", quantify them with other stable experiences we can use as reference units, then select the operations on them which happen to have predictive value. If you experience pushing this object that feels to weigh 1kg with a force that feels like 1 N, you are going to experience seeing it accelerate at 1m/s^2. |
