| inertia | an object's tendency to resist change in motion; 惯 性 |
| momentum | force or speed of movement; impetus |
| First Law | Objects keep on doing what they are doing. |
| inertia | 惯 性,You can stop peddling a bike and will continue moving forward. |
| Third Law | 每 一 个 作 用 力 都 会 有 反 作 用 力 ,When you push something, it pushes back. |
| force | 力, a push or a pull |
| Third Law | Which law allows a rocket to accelerate by burning fuel? |
| First Law | Which law describes what happens when a tablecloth is pulled out from under a plate without damaging it? |
| F=ma | 力 = 质 量 X 加 速 度, equation for calculating force |
| force and mass | Acceleration depends on these 2 things. |
| acceleration | change in motion (speed or dirction) is __ . 加 速 度 |
| First Law | Law of Inertia, 如 果 没 有 加 入 不 平 衡 的 力 ， 静 止 的 物 体 会 永 远 不 动 ， 运 动 的 物 体 会 永 远 匀 速 运 动 |
| Second Law | Which law related acceleration to mass |
| unbalanced force | when the net force of the object does not equal zero |
| balanced force | Forces that cancel each other are __ . |
| Second Law | 力 = 质 量 X 加 速 度, More mass means you need more force to accelerate |
