1. Any object all maintains static or the uniform rectilinear translationcondition, until receives other objects the action to force it tochange this kind of condition.2.The object acceleration gathers the external force which receives withthe object to have the direct ratio, has the inverse ratio with theobject quality, the acceleration direction with gathers the externalforce the direction to be same. 3.The function in two objects pair of action directions opposite, thesize is equal, the function in the identical straight line, thefunction on the different two objects.

牛顿三大定律:Newton's three basic principles The first law describes a fundamental property of matter, called inertia, as follows: Every body remains in a state of rest or in a state of uniform motion (constant speed in a straight line) unless it is compelled by impressed forces to change that state. Newton's second law describes the manner in which a force compels a change of motion, at a rate of change called acceleration. It can be stated as follows: Change of motion is proportional to the impressed force and takes place in the direction of the straight line in which that force is impressed. Newton's third law may be stated as follows: Action and reaction are equal and opposite. This law is often expressed as “for every action there is an equal and opposite reaction.”
