It is a very interesting chapter.Inthis chapter we read about the nomaricles,first law of motion Second Law of Motion and third law of motion. The first law of motion is that the force is unbalanced the second law of motion is equal to mass upon velocity and in third law of motion the force is equal .

thanks
but if you could explain more that could be superb

1st law....an object remains in state of rest unless and until and external unbalanced force i applied......for example....a football ....it remains in rest...unless u kick the ball....2nd law the rate of change of momentum is proportional to the applied unbalanced force.....f=kma, force= mass.acceleration where k is constant
3rd law
for ever action there is an equal and opposite reaction...eimple eg: if u hit ur frnd ...he/she will in return hit u....hope this answer is useful
3rd law

i have not understood the second one
plzz tell
oh i will expain u dat...again
ok
thank u for being this much friendly dear
2nd law mainly states that....the acceleration of the object is directly proportional to the force and inversely proportional to the mass.which means.....We know objects can only accelerate if there are forces on the object... newton's second law tells us exactly how much an object will accelerate for a given net force...
there is a formuale for finding this force...that is wat i explained earlier...f=kma...where k is a constant.....i dont remember whether u have a derivation for dat equation...if so ....to understand better plz refer that...
thank u sooo much
did understand?
did u understand**
