** Atom and Introduction to Nuclear physics ** Introduction Alpha-particle scattering 2.1 Experimental set-up ➢ Alpha particle o is a high-energy helium nucleus with 2 protons and 2 neutrons. o has 2 positive charges. ➢ Gold foil was chosen since it has a high atomic mass. Thin gold foil‚ ~10-6m was bombarded by high-energy alpha particles. ➢ Angular deflections/ scattering of alpha particles were measured by observing

below a certain temperature. Once in motion‚ an electrical current will flow in a closed loop within a superconducting material. This is the closest to scientists of a perpetual motion machine. In 1911‚ Heike Kamerlingh Onnes first observed superconductivity. He used mercury and cooled to four degrees Kelvin. When the mercury reached that temperature‚ the resistance disappeared. That meant that the electrical current flowed freely through it. In 1933‚ the “Meissner effect” was discovered.

We can relate physics to softball in many different ways. It is actually hard to not think about the game of softball without some physics in mind. Specifically‚ the ideas of momentum and energy helps define the way softball works and why it works. Momentum Running: When running the bases in softball‚ there is a lot more to it then the average person would think. While we run the bases‚ we are changing our momentum by applying more force‚ the force of friction‚ onto the ground which causes more

1.1 GRAVITY AND GRAVITATIONAL FIELDS 1.1.1 Define weight as the force on an object due to a gravitational field. Weight is the force experienced by an object due to the presence of a gravitational field. This force is directly related to the strength of the gravitational field acting on an object and the mass of that object. m = mass‚ g = acceleration due to gravity m = mass‚ g = acceleration due to gravity Fg = mg Fg = mg 1.1.2 Explain that a change in gravitational

Physics of Volleyball Physics is the study of energy and how it is transferred from one particle to another. There is certainly a lot of energy transferred between objects and players in the sport of volleyball. A few of the concepts of physics that take place during volleyball include gravity‚ displacement‚ velocity‚ acceleration‚ projectile motion‚ and force. These concepts are displayed throughout the different positions on the court. There are three main aspects of volleyball that include
