19 de may. de 2024 · Mach speed is a unit of measurement used to compare an object’s velocity to the speed of sound in the surrounding medium. Mach 1 represents the speed of sound. For example, Mach 2 is twice the speed of sound. The current fastest manned aircraft, the North American X-15, reached a maximum velocity of Mach 6.7, or about 7,273 kilometers per hour.

Hace 1 día · Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows: . A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by a force.

The laws modified the heliocentric theory of Nicolaus Copernicus, replacing its circular orbits and epicycles with elliptical trajectories, and explaining how planetary velocities vary.
