Newton's first law expresses the principle of inertia: the natural behavior of a body is to move in a straight line at constant speed. A body's motion preserves the status quo, but external forces can perturb this. The modern understanding of Newton's first law is that no inertial observer is privileged over any other. The concept of an ...
Christmas card with holly Jacques Hnizdovsky Christmas card. During the first 70 years of the 19th century it was common for Christmas and other greeting cards to be recycled by women's service organizations who collected them and removed the pictures, to be pasted into scrap books for the entertainment of children in hospitals, orphanages ...
Newton also formulated an empirical law of cooling, which was the first heat transfer formulation and serves as the formal basis of convective heat transfer, [19] made the first theoretical calculation of the speed of sound, and introduced the notions of a Newtonian fluid and a black body.

English: In this image, Newton's Laws of Motion are shown throughout common occurrences of a soccer match. In the first law, the ball is influenced by the wind, an unbalanced force, causing it to roll. In the second law, the ball is being kicked causing its acceleration to be dependent on the mass of the soccer ball and the net force of the kick.
Succinctly stated, Newton's law of gravitation states that the force on a spherical object of mass due to the gravitational pull of mass is = ^, where is the distance between the two objects' centers of mass and ^ is the unit vector pointed in the direction away from the center of the first object toward the center of the second object.
