Could you also please clarify the statement V2 " So if we apply external force on object nothing but a action "?
It's the rule of Phys. But, beyond the rule, we have to help. There where teachers, books, etc. This is why people apply to this forum. Add a comment. Active Oldest Votes. Improve this answer. PhotonBoom 5, 2 2 gold badges 14 14 silver badges 32 32 bronze badges.

The equation works both ways. The velocity, force, acceleration, and momentum have both a magnitude and a direction associated with them. Scientists and mathematicians call this a vector quantity.
The equations shown here are actually vector equations and can be applied in each of the component directions. We have only looked at one direction, and, in general, an object moves in all three directions up-down, left-right, forward-back.
His third law states that for every action force in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions. An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
The acceleration of an object depends on the mass of the object and the amount of force applied. Whenever one object exerts a force on another object, the second object exerts an equal and opposite on the first. Examples of inertia involving aerodynamics: The motion of an airplane when a pilot changes the throttle setting of an engine. The motion of a ball falling down through the atmosphere. A model rocket being launched up into the atmosphere.

The three laws proposed by Sir Isaac Newton concerning relations between force, motion, acceleration, mass, and inertia. These laws form the basis of classical mechanics and were elemental in solidifying the concepts of force, mass, and inertia.
This law is also called the law of inertia. Thus, if one body exerts a force F on a second body, the first body also undergoes a force of the same strength but in the opposite direction. This law lies behind the design of rocket propulsion, in which matter forced out of a burner at high speeds creates an equal force driving the rocket forward.
