Question

class 11 chapter 5 law of motion what is momentum what is inertia what is impulse in very simple language and with numerical question as a example

Answer 1

linear momentum : The product of mass and velocity is known as linear momentum.
it's unit is kg m/s.
________________________
inertia : it is the property to maintain it's position.it depends upon the mass of the body.
there are three types of inertia:
1)inertioa of rest : it is the property to maintain it's rest state.
2)inertia of motion : it is the property to maintain it's motion.
3) inertia of direction : it is the property to maintain the direction of motion.
_________________________
impulse : the product of impusive force and time is called impulse.
it's SI unit is N-s.
_______________________
nawton's laws of motion:
1) newton's first law of motion:every body wants to continue in it's motion.
2)Newton's second law of motion: The rate of change of liner momentum is called force.
3) Everybody applies equal and opposite force on each other .
