What are the three Newton 's laws of motion. Explain breifly.
Answers
Newton's laws of motion relate an object's motion to the forces acting on it. ... In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.
Newton's 1st law of motion...
➜ 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.
➝ Example :-
- Objects in motion stay in motion and objects at rest stay at rest unless acted upon by an outside force (unbalanced force).
- A stationary ball will stay stationary unless acted upon by a force. A stationary object with no outside force will not move.
- With no outside forces a moving ball will continue moving in the same speed and direction With no outside forces, a moving object will not stop.
Newton's 2nd law of motion...
➜ Newton's second law of motion can be formally stated as follows: 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.
➝ Example :-
- Pushing a car is easier than pushing a truck with the same amount of force as the mass of the car is lesser than the mass of the truck.
Newton's 3rd law of motion...
➜ Newton's third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.
➝ Example :-
- You hit the wall with a force, and that exact same amount of force is returned by the wall. While Rowing a boat, when you want to move forward on a boat, you paddle by pushing the water backwards, causing you to move forward.
