2. 物体的受力情况- 单个物体的受力情况：- 物体的重力：受地球吸引而产生的力。
- 物体的弹力：物体受到其他物体施加的弹性力。
- 物体的摩擦力：物体与其他物体之间的接触面产生的力。
- 多个物体的受力情况：- 物体的支持力：物体受到支撑物对它的支持力。
- 物体的重力：受地球吸引而产生的力。
- 物体的摩擦力：物体与其他物体之间的接触面产生的力。
3. 力的合成与分解- 力的合成：若两个力的方向相同，则两个力合成的力等于两个力的矢量和；若两个力的方向不同，则两个力合成的力等于两个力的矢量差。
- 力的分解：将一个力分解为两个方向上的力分量。
4. 牛顿第一定律- 牛顿第一定律又称为惯性定律，内容如下：- 如果一个物体不受外力的作用，或受到的外力平衡时，物体将保持静止或匀速直线运动的状态。
- 物体的惯性是指其保持静止或匀速直线运动状态的性质。
5. 牛顿第二定律- 牛顿第二定律又称为运动定律，内容如下：- 物体的加速度与物体所受合外力成正比，与物体的质量成反比。
- 物体的加速度的方向与物体所受合外力的方向相同。
- 物体的质量越大，给它相同的加力，加速度越小；物体的质量越小，给它相同的加力，加速度越大。
6. 牛顿第三定律- 牛顿第三定律又称为作用-反作用定律，内容如下：- 两个物体之间的相互作用力，大小相等、方向相反，并且作用在两个相互作用物体上。
