Question

state the all newton's law of motion and law of conservation of momemtum​

Answer 1

$\large{\underline{\underline{\bold{\bf{Answer:}}}}}$

1. Newton’s 1st law states that a body at rest or uniform motion will continue to be at rest or uniform motion until and unless a net external force acts on it.
2. Newton’s 2nd law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. (F  = ma)
3. The Newton’s 3rd law states that for every action there is an equal and opposite reaction.

law of conservation of momentum:

Consider two colliding particles A and B whose masses are m1 and m2 with initial and final velocities as u1 and v1 of A and u2 and v2 of B. The time of contact between two particles is given as t.

($m_1u_1+m_2u_2=m_1v_1+m_2v_2$)

pls mark as brainliest

Answer 2

Explanation:

first laws of motion :

an object continues to be in a state of rest or of uniform motion along a straight line unless acted upon by an unbalanced force.

second laws of motion :

tge rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.

third laws of motion :

to the every action, there is an equal and opposite reaction and they act on two different bodies.

Laws of conservation of momentum

_______________________________

Laws of conservation of momentum states that. For two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied. Therefore, momentum can neither be created or nor be destroyed.
