newton's three laws of motion(牛頓三大運動定律)
1、Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
無外力的作用下，物體保持靜止狀態
2.The relationship between an object's mass m,it's acceleration a,and the applied force F is
F=ma (力、質量、加速度的關係)
Acceleration and force are vectors(as indicated by their symbols being displayed in slant bold font);in this law the direction
of the force vector is the same as the direction of the acceleration vector.
3.For every action there is an equal and opposite reaction.
作用力與反作用力的關係，方向相反，大小相等
