Question

write the answer no. 4

Answer 1

first law is
law of inertia
second law
law of momentum
third law
every action have a equlent and opposite reaction

Inertia means tendency of a body to move back and front with same mass and velocity
example:- a person standing in a bus can experience when the sudden break is applied

Movementum:- movement of a body with a mass and velocity
example:- it applies when the velocity of a body in motion

Every action has a equlent and opposite reaction it means
example:-when we hit the floor with our hand the action is hitting the floor the reaction is when we hit, the same force will applied from the floor to our hand

Answer 2

First law of motion =an object continue to be in a state of rest of uniform motion unless acted upon by an unbalanced force.
second law of motion = The rate of change of momentum of an object is directly proportional to the applied force in the direction of the force.
Third law of motion = To every action,there is an equal and opposite reaction and they will act on two different bodies
