- The second (symbol: s) (abbreviated s or sec) is the base unit of time in the International System of Units / Système International d'Unités (SI). It is qualitatively defined as the second division of the hour by sixty, the first division by sixty being the minute. The SI definition of second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.

- The second law of thermodynamics states that whenever energy is transformed from one form to another form, entropy increases and energy decreases. In other words: over time, differences in temperature, pressure, and density tend to even out in a horizontal plane, but not in a vertical plane due to the force of gravity.

Newton's 2nd Law Quantitatively, Newton's second law predicts that when there is an unbalanced force on an object or system, resulting acceleration will be directly proportional to the net force while inversely proportional to the object or system mass.F net = (m system)a (Eq. 1).hat is, the object will have an acceleration (change in velocity). This is the basis for Newton's Second Law of Motion. Newton's Second Law deals with the relationship between cause and effect: what causes an object to change its motion (the effect).

Force and Motion: Facts Newton's Second Law Newton's second law of motion states that a force, acting on an object, will change its velocity by changing either its speed or its direction or both. If your basketball goes rolling into the street and is hit by a bike, either the ball will change direction or its speed or both.

second (s or sec) The second (abbreviation, s or sec) is the Standard International ( SI ) unit of time. One second is the time that elapses during 9,192,631,770 (9.192631770 x 10 9 ) cycles of the radiation produced by the transition between two levels of the cesium 133 atom. There are other expressions for the second. It is the time required for an electromagnetic field to propagate 299,792,458 meters (2.99792458 x 10 8 m) through a vacuum. This figure is sometimes rounded to 3.00 x 10 8 m, or 300,000 kilometers (3.00 x 10 5 km).

- Second ionisation energy is defined by the equation: It is the energy needed to remove a second electron from each ion in 1 mole of gaseous 1+ ions to give gaseous 2+ ions. More ionisation energies. You can then have as many successive ionisation energies as there are electrons in the original atom.t is the energy needed to remove a second electron from each ion in 1 mole of gaseous 1+ ions to give gaseous 2+ ions. More ionisation energies. You can then have as many successive ionisation energies as there are electrons in the original atom.

Module 22: Metabolism The form of energy associated with the position or arrangement of objects in a system. Second Law of Thermodynamics. States that no enrgy transformation is perfectly effiecients; in a closed system, some energy from every transformation will always be lost as heat, with a corresponding increase in entropy.

Force, Mass & Acceleration: Newton's Second Law of Motion That situation is described by Newton's Second Law of Motion. According to NASA, this law states, Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration. This is written in mathematical form as F = ma. F is force, m is mass and a is acceleration.

Physics Physics is the study of energy and matter in space and time and how they are related to each other. Physicists assume the existence of mass, length, time and electric current and then define (give the meaning of) all other physical quantities in terms of these basic units.

- This leads to the second law of thermodynamics and the definition of another state variable called entropy. The second law stipulates that the total entropy of a system plus its environment can not decrease; it can remain constant for a reversible process but must always increase for an irreversible process.

- LAWS OF PHYSICS. The basic laws of physics fall into two categories: classical physics that deals with the observable world (classical mechanics), and atomic physics that deals with the interactions between elementary and sub atomic particles (quantum mechanics). The basic laws of both are listed here in alphabetical order.

What is the differences between first and second ionization energy? 2nd ionization energy refers to the energy needed to remove a second electron. By the time an atom has lost its first electron (adding energy enough to equal the first ionizat … ion energy), it has become positively charged. This means, it is looking for electrons because it wants to be neutral.

- Best Answer: The second ionization energy is the energy needed to remove the second electron from an atom. In some cases this will require a great deal of energy because the second electron will come from a lower energy level. Such is the case for sodium.
