Question

newton 1st , 2nd , 3rd law

Answer 1

Newton's first law:

   Newton's first law- also called the " the law of inertia", states that an object at rest remains at rest, and an object that is moving will continue to move straight and with constant velocity, if and only if there is no net force acting on the object.

  Eg: Wearing a seat belt in a car while driving.

Newton's second law:

   Newton's second law describes a simple relationship between the acceleration of an object with mass m, the net force Fnet acting on that object.

                                         Fnet= ma

   Eg: Riding your cycle.

Newton's third law:

    Newton's third law states that all forces between two objects exist in equal magnitude and opposite direction: if one object A exerts a force FA on the second object B, then B simultaneously exerts a force FB on A, and the two forces are equal in magnitude and opposite in direction.

   Eg: As a professor paces in front of a whiteboard, he exerts a force backward on the floor.

                                       FA= FB
