Newton's 1st law is about an object that rest or in uniform motion in a straight line unless acted upon by an external force.
Example of Newton's 2st Law
For example, when a cup is on a table, the cup has gravity that affects the table which doesn't let the cup move, and the external force is the hand that will hold the cup on the table.
What is Newton's 3st Law?
Newton's 2st law is the acceleration of an object as produced by a net force.
Example of Newton's 3st Law
For example, when a car is moving and starts to accelerate, it changes speed due to the energy produced by the engine.
Newton's Third Law is the action force that is acting upon something. When the car hits the wall, the wall pushes back the car.
For example, when two cars crashes each other, that describes the relationship between two bodies and the forces acting upon them. When the Blue car and the Red car crashes upon them, the Blue car pushes the Red car and the Red car pushes the Blue car back.
