explain newtons 1st,2nd and 3rd law of motion with examples
Answers
Newton's first law of motion:
According to Newton's first law of motion, a body at rest or a body moving in uniform motion along straight line will remain at rest and the body will continue to move in uniform motion until an external unbalanced force is applied.
example : a ball kept on the floor will not move until someone pushes it.
2. According to Newton's second law of motion, force is directly proportional to the applied force.
example: firing of a bullet from a gun
3. According to Newton's third law of motion, to every action , there is equal and opposite reaction.
example : we are ae to walk on the floor because we pushes the ground in backward direction ( action ) and as reaction the ground also pushes us in the forward direction.

Answer:
In the first law, an object will not change its motion unless a force acts 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.
