      @horse_life_tgs well that depends on the force! Strictly speaking, when you weigh yourself on some bathroom scales, you are measuring the force of your mass being pulled towards the Earth. You can measure the acceleration due to gravity fairly accurately with just a small mass (like a conker) attached to a piece of string and a stop watch! The other forces of nature require more elaborate set-ups to measure the forces.

      The metric unit of force is the Newton, which is measured in units of kilogram meters per second per second – and it’s basically a unit describing the amount of force you need to exert to increase the speed of a kilogram weight by one meter per second in one second. (Not super intuitive, but it’s useful!) With that as a standard scale, you can compare all forces by using this as a relative value!
