Can anyone help me in understanding laws of motion\'s basics |
| Answer» Three Laws of Motion:-----(1.) First Law, when an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their states of motion unless a force acts to change the motion.(2.) Second Law, In an innertial refference frame, the vector sum of the forces (F) on an object is equal to the mass (m) of that object multiplied by the acceleration (a) of the object F=ma. ( It is assumed here that the mass (m) is constant. )(3.) Third Law, When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body. | |
