发表时间:2025-03-12 15:21 Newton's laws 牛顿定理 伴奏方案1 [verse] First law 第一定理
is about everything has an inertia 是关于任何事物都有惯性 object tends to keep its own motion 物体倾向于保持原有的状态 keeps the same speed and direction 保持同样的速率和方向 direction
[rap] That means if an object is still 这意味着如果物体静止 it will aways keep in still 它将保持静止 if an object moves 如果它运动 it will always keep in move 将保持运动 unless affected by force, 直到受到力的作用 which came from everything (力)可能来自任何事物 this is the first law 这个是第一定理 that applies to everything 适用于任何情况 [choir] Force cause the changes 力带来改变 that affect the motion of everything 改变任何物体的运动 Either from still or moving 不管是运动还是静止 Newton's first law 牛顿第一定理 law of the motion 运动的定理
[verse] Second law 第二定理 is about the result of the net force 说的是合力 equation of the net forces on the motion 运动物体的合力公式 mass multiplied by acceleration 等于质量乘以加速度 leration [rap] this means a higher force will faster accelerate 这意味着更大的力带来更大的加速度 also a higher mass will slower accelerate 更大的质量会有更小的加速度 if no resultant force will not accelerate 没有合力没加速度 unless affected by force that changes of motion states 除非合力不为0才会有加速度改变运动状态 [choir] Force causes the changes that affect the motion of everything Either from still or moving Newton's second law law of the motion [verse]
Third law 第三定理 is about forces of reaction 说的是反作用力 forces come in pairs with their reaction 力和它们的反作用力成对出现 same magnitude opposite directions 大小相等方向相反 direction [rap] This mean the force on you 这意味着我对你的力 is same with yours on me 和你对我的一样 with same in magnitude 大小相同 and reverse direction 方向相反
if in a close system 如果处于封闭系统 with no external force 不受外力 the all internal forces 则内部的力 will cancel themselves all 会相互抵消 [choir] Force causes the changes that affect the motion of everything Either from still or moving Newton’s third law law of the motion
