"Work and energy"

Download file to see previous pages em corresponds to the net force that is the gravity, friction, and resistance through acting on the particle possessing kinetic energy either gained or lost by the prevailing particle.
In a mechanical system, energy is neither generated nor devastated but is can be shifted from potential energy to the kinetic energy or from kinetic to potential. For an isolated system, there is the application of the Work-Energy Theorem states that any alteration in the total energy of a system occurs because of work. In case the system works on the outside the universe, then the W is positive, and the corresponding energy required executing work emanate from the system. Moreover, in case work done is done from the outside the system then W becomes negative and the energy of the system escalates.
In case no work is done, the total energy of the underlying system does not alter. Taking a mass on the inclined plane and attached to the spring. The system gives two potential energies emanating from gravity and spring (Chen,pp.124-189). Concisely, the gravitational potential equivalent to the corresponding work demanded to the place the object at that height represented as PEg=mgh. Taking the height h, distance x and the angle θ, gravitational potential becomes PEg= mgxsinθ
The underlying computer was booted in the bid to make the first set of the measurements. Motion Sensor’s phone plugs were connected to the Digital Channels 1 and 2. Yellow-branded (pulse) was filled into Digital Channel 1. Moreover, plug (echo) was also connected to the Digital Channel 2. The track was placed on the horizontal surface, and the lab jack was placed at one terminal track to the raise that ends. The end stop for the track ought to be placed at the higher end of the track so that the underlying magnets face away from the prevailing the track. The angle indicator was used to measure the incline angle of the track and recorded in the table. Motion Sensor was mounted at the low end of the track, and ...Download file to see next pagesRead More

Work,Energy,and Efficiency: Pulleys
The increase the efficiency of double movable pulley (1.24) followed by single movable pulley (2.1) the lastly single fixed pulley (1.74). Each pulley in the system cause friction and hence increases the total energy applied in the lifting of loads; double movable pulley has

Chemistry Practice - Bonding energy kinetics
Chlorine will have the tendency to form the anion, Cl-. There will be no sharing of electrons, hence giving rise to an ionic bond. Iodine is in Group VII and has 7 electrons in its outer shell, one of them being unpaired. A single bond will be formed between two iodine atoms, with an equal sharing of these two outer shell electrons.
