Newton’s First Law of Motion An object at rest will remain at rest and an object in motion will continue moving at a constant velocity unless acted upon by an unbalanced force. Things are LAZY…they keep doing what they’re already doing unless an UNBALANCED force causes a change! The La...
第一定律 第2章牛顿运动定律（Newton’slawsofmotion）任何物体都保持静止的或沿一条直线作匀速运动状态,除非作用在它上面的力迫使它改变这种状态。问题:1.第一定律涉及了哪两个基本概念?答:惯性和力。2.第一定律定义了一个什么样的参考系?答:惯性参考系。3.一艘船在一个风平浪静的海面上匀速的航行,某人站...

Newton’s Third Law of Motion Rocket propulsion can also be explained using Newton’s third law: hot gases from combustion spew out of the tail of the rocket at high speeds. The reaction force is what propels the rocket. Note that the rocket does not need anything to “push” against. ...
Newton’s 1st Law An object at rest remains at rest, and an object in motion remains moving at that velocity, unless a net external force causes the motion to change. We often refer to Newton’s first law as the law of inertia. ...
Newton’s 1st Law of Motion An object at rest will remain at rest, and an object in motion will continue its state of uniform motion until an outside net force acts on it. So what does this mean??? Objects are in a state of equilibrium as long as they do not experience a net for...
