These laws systematically describe the relationship between applied forces and the motion of objects\u2014from rest and uniform motion to changes in velocity. As a result, for the first time, humans were able to explain motion through clear scientific laws rather than relying on intuition or fragmented observations.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Kh\u00f4ng d\u1eebng l\u1ea1i \u1edf \u00fd ngh\u0129a h\u1ecdc thu\u1eadt, \u0111\u1ecbnh lu\u1eadt Newton c\u00f2n g\u1eafn li\u1ec1n v\u1edbi \u0111\u1eddi s\u1ed1ng h\u1eb1ng ng\u00e0y.
