different lengths of string that are to be tied together make a pendulum. Then I would ask the 10-year-old if he can solve the problem of which combination would swing the fastest taking into consideration the height at which it would dropped at. If the 10-year-old does trial and error without much planning‚ then the 10-year-old would be a concrete operational thinker. If the 10 year conducts many trials but fails to answer why the pendulum swings faster with a shorter string‚ then he would answer the

a simple pendulum at the end of an arm that is 0.500 m long. The astronaut counts exactly 47 full swings in 1.00 min. What is the value of g? 79. The frequency of the second hand on a clock is __________. 80. A simple pendulum has a string that is 20.0 cm long with a 100.0-g mass suspended from the end. Pulling the mass 2.0 cm to one side and releasing it starts the pendulum in motion. a. What is the amplitude of this pendulum? b. What is the period of this pendulum? c. If the

In the postclassical era or medieval period (1 CE to 1500 CE)‚ there were a myriad of advances‚ methods‚ depictions and detailed accounts of historical timekeeping devices. This was a time of changing cultures‚ religions and ideologies‚ and society as whole had a thirst for knowledge i.e. the Middle East‚ Europe‚ India‚ Japan and China. Acquiring new knowledge and technological advancements‚ allowed certain empires‚ during this time‚ to rise above others. Timekeeping was a unifying factor. Timekeeping

this you may use the “variable-method” structure‚ e.g. “Measuring a car’s acceleration using a pendulum.” Here the variable is the gravitational acceleration and the method is the simple pendulum. Another way is to use the “dependent-independent variable” structure‚ e.g. “Angular displacement of a pendulum in an accelerating car.” Here the dependent variable is the angular displacement of a pendulum and the dependent variable is the car’s acceleration. Note: do not mention any keyword in the

Harwood December 19‚ 2011 Background Before quartz watch‚ to get accurate time‚ people use pendulum clocks and mechanical watches. The trouble with them is that they will stop if people cannot remember to wind them. They are also not absolutely accurate because their dependence on the force of gravity which is a little different between places with different altitudes‚ as well as the length of pendulums is effected by temperature. A Quartz Watch All these problems are solved by quartz watch.

Throughout my report I will inform about the significance and influence Galileo had on the Scientific Revolution. Galileo was the inventor of the scientific method. As well as studying the phases of Venus and discovering the moons of Jupiter‚ Galileo studied one of the simplest break throughs to ever occur- the swinging pendulum. Legend has
