Definition of newton s first law
What is newtons 1st law and what does it say?
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. This tendency to resist changes in a state of motion is inertia. There is no net force acting on an object (if all the external forces cancel each other out).
What would be example of Newton's first law?
One of the finest examples of Newton's first law of motion is an object that is simply placed on the surface of the earth. The natural tendency of the object is to maintain its state of rest until a force acts on it. For instance, a book kept on a bookshelf does not change its shape, size, or position until acted upon by an external force.
What is the significance of Newton's 1st law?
Newton's first law explains how things move and how forces work on their movement, which makes it an extremely important discovery. If we were to place an object into space, we could observe how it behaves without any external influences. The force that is exerted upon an object can be either external or internal.

fact sheet Newton’s laws of motion Newton’s first law of motion Objects remain in their state of rest, or uniform motion in a straight line, unless an external unbalanced force acts on them. This is sometimes called the principle of inertia. Inertia is the tendency of an object to resist a change in its state of motion.

Law 1 Every body continues in it’s state of rest or of uniform rectilinear motion except if it is compelled by forces acting on it to change that sate. Law 2 The change of motion is proportional to the applied force and takes place in the direction of the straight line along which that force acts. Laws 3

Newton’s First Law of motion states that a body at rest will remain at rest unless acted upon by an unbalanced force. It also states that a body in motion will maintain that motion, in the same direc- tion and with the same speed, unless acted upon by an unbalanced force. About this Poster

Newton’s First Law states that there is no physical way to distinguish between whether we are moving or the station is moving, because there is nearly zero total force acting on the body.
