24Centrifugal force (planar motion) — In classical mechanics, centrifugal force (from Latin centrum center and fugere to flee ) is one of the three so called inertial forces or fictitious forces that enter the equations of motion when Newton s laws are formulated in a non inertial… …
25Kepler's laws of planetary motion — In astronomy, Kepler s Laws of Planetary Motion are three mathematical laws that describe the motion of planets in the Solar System. German mathematician and astronomer Johannes Kepler (1571–1630) discovered them.Kepler studied the observations… …
26Simple harmonic motion — is the motion of a simple harmonic oscillator, a motion that is neither driven nor damped. The motion is periodic, as it repeats itself at standard intervals in a specific manner described as being sinusoidal, with constant amplitude. It is… …
27Reciprocating motion — also called Reciprocation, is an up and down (or back and forth) motion which repeats over and over again. It is seen in a wide range of reciprocating engines and pumps.A Crank (mechanism) can be used to turn circular motion into reciprocating m …
28Polar motion — is the movement of Earth s rotation axis across its surface. This is measured with respect to a reference frame in which the solid Earth is fixed (a so called Earth centered, Earth fixed or ECEF reference frame). This variation is only a few… …
29Illusory motion — The term illusory motion, also known as motion illusion, is used to define the appearance of movement in a static image. This is an optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color… …
