I. Temperature Measurement 1. A thermometric property is a physical property that changes in a known way with temperature‚ and can therefore be used to measure temperature. The substance used as a thermometer must have a property that varies proportionally / linearly with temperature. [ In other words: When objects are heated or cooled‚ their temperatures change‚ along with some of their properties‚ these properties are known as Thermometric Properties.] Two commonly used thermometric properties

Objectives: • To be able to explain how the photoelectric effect experiment works and why a photon model of light is necessary to explain the results. • To study the effect of intensity of light on photoelectric experiment. • To estimate the Planck’s constant‚ h through the simulation. • To be determine how to calculate the wavelength of light‚ the work function of the metal‚ or the stopping potential‚ if given the other two. Beginning with the plate made of sodium. Keep all the parameters

logger Variables: Independent: the mass pulls down the frictionless trolley. Dependent: the time taken when the frictionless trolley travel through two light gates. Fix: the distance of the light gates and the height of the light gates. Uncertainties: The strength of the plastic string after pulling a lot of weights. Procedure: 1. Put two light gates 50 cm between each other‚ the lights gates hanging by the clamps. 2. Hang the string one side to the frictionless trolley and another

Presentation In Physics Objectives: 1. To answer the following questions: What is an investigatory project ? Why do 4th year students make an investigatory project ? Why did we choose our investigatory project ? To defend our investigatory project. What is an investigatory project ? An investigatory project is also known as an experimental project and is one which is used to show how something might happen if certain conditions are added to it. It can also be used to investigate why

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

Lab 3: Experimental Design & Hypothesis Testing 1. Some observations found about termites are that they live in moist‚ dark environments‚ they are sterile and lack eyes‚ and their primary task is to collect food. From this information the hypothesis that due to their lack of eyes‚ they use feeling of their skin to find what they are searching for and a pencil line would give a feeling of wood that would attract the termites. By making a course that split into two paths of a pen line and pencil line

Physics of Sports A sport isn’t just about winning; it is also about strategy‚ how the game is played‚ and performance of the athletes. Physics is the last topic many people associate with sports. However‚ physics can be applied to every aspect of any sport‚ which is a study referred to as Sports Science. Components of this study include gravity‚ projectile motion‚ acceleration‚ force‚ vectors‚ etc. With new technology that physics in sports introduce‚ more possibilities of physical science can
