He strongly adhered to the principle that more force was required to move a weight than was required to keep it in motion, so dynamics and statics had to be two separate subjects. Galileo would later show how to unify statics and dynamics.
Siya Matindi adhered sa prinsipyo na mas lakas ay kinakailangan upang ilipat ang isang timbang kaysa noon ay kinakailangan upang panatilihin ito sa kilos, kaya dinamika at estatika nagkaroon na ng dalawang magkahiwalay na mga paksa. Galileo ay mamaya ipakita kung paano sa pagsamahin estatika at dinamika.
