Question

Newton's three laws of motion with applications

Answer 1

(1.) Newton's first law of motion------
• If a body is at rest, it remains at rest unless a force is applied on it.
•If a body is moving, it will continue to move with the same direction unless a force is applied on it.
• Newton put the above observations in the form of a law which is called the NEWTON'S FIRST LAW OF MOTION.

(2.) According to Newton's second law of motion------
• The rate of change of momentum of an object is directly proportional to the resultant force acting on the body and is in the same direction.
• This law means that the force of the object moving will be equal to the opposing force such as air resistance.
• For example, A skydiver jumps from a plane and accelerate until he reaches the highest velocity possible, when this happens his acceleration is equal to the downwards forces of the skydiver.

(3.) According to Newton's third law of motion--

• "All forces occur in pairs, and these two forces are equal in magnitude and opposite in direction."
•It can be said that, Every action has opposite amount of force, thus, either we move or does the wall move.

This is simple terms is that to every action force there is an equal, but still the same, reaction force. For example, if one pressed on a wall a equal and same force is pushed back at them.



I HOPE THIS WILL HELP YOU.

Answer 2

{Hello}

Newton's first law motion : every inanimate object continues to be in a state of rest or of uniform motion in a straight line unless it is acted upon by an external unbalanced force

-----

Newton's second law of motion : the rate of change of momentum is directly proportional to the applied force and it takes place in the direction of force

------

Newton third law of motion: To every action there is always instantaneour,equal and opposite reaction
