state all three laws of motion explain each law with an example

LAWS OF MOTION:-
1.Newton’s first law of motion:- It states that “an object at rest will stay at rest and an object in motion will stay in motion with the same speed and direction unless acted upon by unbalanced force.” This law is also known as law of inertia. Inertia is a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
2.Newton’s second law of motion:- It 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. In other words it means the force exerted by a body is product of its mass and acceleration.
3.Newton’s Third law of motion:- It states that “If there is force F being applied on a body ,the body will apply a force of equal magnitude but in opposite direction.” or “For every action, there is an equal and opposite reaction.” Simple isn't it?
1st LAW
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
For example: If you slide a hockey puck on ice, eventually it will stop, because of friction on the ice.
2nd LAW
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
For example: If the forces acting on a body is balanced (or cancel each other out) then the body won't accelerate in any direction.
3rd LAW
The third law states that for every action (force) in nature there is an equal and opposite reaction.
For example:A jet moves forward when the exhaust moves backward.
