The first law states that if the net force the vector sum of all forces acting on an object is zero then the velocity of the object is constant.
First law of motion definition in hindi.
Sir isaac newton published three laws in the 17 th century.
Newton s first law of motion is also known as the law of inertia.
Similarly if the object is at rest it will remain at rest unless an unbalanced force acts upon it.
Newton s first law of motion.
Newton s first law of motion also known as the principle of inertia says every body perseveres in its state of being at rest or of moving uniformly straight forward except insofar as it is compelled to change its state by forces impressed 1 i will argue that inertia is an inherent principle and that inertia and newton s first law are in this way natural in the aristotelian sense.
This video is all about newton s first law of motion.
Understanding first law with an example frequently asked questions.
The video is on newton s 1st law of motion i e.
It gives real life examples of inertia and application of newton s first law of motion.
From this you can easily clear your doubt grasp concept.
This law does an introduction of motion of the object and the force acting on it.
Velocity is a vector quantity which expresses both the object s speed and the direction of its motion.
Newton s first law states that if a body is at rest or moving at a constant speed in a straight line it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force this postulate is known as the law of inertia the law of inertia was first formulated by galileo galilei for horizontal motion on earth and was later generalized by rené descartes.
Therefore the statement that the object s velocity is constant is a statement that both its speed and the direction of its motion are constant.
Newton s first law of motion states that an object in motion tends to stay in motion unless an external force acts upon it.
