third law of motion

(a) State Newton's third law of motion and give two examples to illustrate the law. (b) Explain why, when a fireman directs a powerful stream of water on a fire from a hose pipe, the hose pipe tends to go backward.

A person throws an object on a horizontal frictionless plane surface. It is noticed that there are two forces acting on this object-(i) gravitational pull and (ii) normal reaction of the surface. According to the third law of motion, the net resultant force is zero. Which one of the following can be said for the motion of the object?

According to the third law of motion, when we push on an object, the object pushes back on us with an equal and opposite force. If the object is a massive truck parked along the roadside, it will probably not move. A student justifies this by answering that the two opposite and equal forces cancel each other. Comment on this logic and explain why the truck does not move.

State secound law of motion and show that second law is the real law of motion .

Show that Newton's second law of motion is the real law of motion.

For rotational motion, the Newton's second law of motion is indicated by :-
