the three laws of motion are-
Newton's First law of motion
Newton's second law of motion
Newton's third law of motion
According to Newton's first law of motion if a body is at rest it will remain at rest and if a body is in motion it will remain moving in the same direction in the same speed unless an external force acts on it.
According to Newton's second law of motion the rate of change in momentum is directly proportional to the force applied on it and the change in momentum takes place in the direction in which the force is applied.
According to Newton's third law of motion to every action there is always an equal and opposite reaction

And define impulse and state its si unit also give ans
according to classical mechanics Impulse is the integral of force over the time interval for which it acts
It's SI unit is Newton second

the three laws of motion are:-
1.Every body continues to be in its state of rest or uniform motion in a straight line unless it is compelled by some external force to change that state.
2.the rate of change of momentum of a body is directly promotional to the net external force applied on it and the change in momentum takes place in the direction in which the force is applied.
3.To every action there is an equal and opposite reaction; action and reaction forces act on different bodies.
Impulse applied to an object produces an equivalent vector change in its linear momentum , also in the same direction. Its SI unit is newton second
