Physics Notes on NEWTON’S LAWS OF MOTION for SSC & Railway

First Law: Everybody maintains its initial state of rest or motion with uniform speed on a straight line unless an external force acts on it. It is also called Galileo’s
law or law of inertia.
Example While jumping from a slowly moving train/bus one must run for short distance, in the direction of motion.
• Second Law: The form acting on an object is directly proportioned to the product of the mass of the object and the acceleration produced on it.
• Third Law: To every action, there is an equal and opposite reaction.
Example : Bogies of the trains are provided with buffers to avoid severe jerks during shunting of trains. Rocket moves up due to reaction of downward ejection of gas.
