Centripetal Force By: Alexander Jones Abstract In this experiment Newton’s first and second laws of motion were used to study and verify the expression for the force, F, to be provided to mass, m, to execute circular motion. Two experimental conditions were measured using 1) a simple pendulum and 2) a rotating table. To acquire data regarding force, period, and velocity of the experimental setups a force sensor and photogate motion sensor were employed. The data was then analyzed graphically […]
Written by: Jeremy Stimack Introduction The analysis of the movement of a person has several powerful applications in determining the various biomechanical phenomena that occur within the body, such as joint motion or forces in the hip. Such information can provide valuable feedback in the research and development of medical devices that aid to remedy mechanical issues in affected individuals. Therefore, the objective of experimentation was to gain experience with a kinematic linkage system that is capable of measuring such […]
To solve a mechanics problem, you should read the problem carefully and attempt to relate it to theories you’ve learned. Draw accurate diagrams and write out the problem data. Next, apply physical principles you have learned such as Newtons Laws, and tabulate mathematical equations. Double check to make sure your equations are dimensionally homogeneous: a fancy way to say that they have similar units on either side of the equals sign. Solve your equations and check your solution if possible. […]
In a wave energy can move from one place to another, however the actually matter particles will return to its original place (1). The waves however don’t go back to their original place but go to their desired location (2). The reason why the transport of matter doesn’t exist is because you would need other matter to move or other matter to have a force which would cause the other object to move (1). The differences between transverse and longitudinal […]
In Galileo’s Dialogues Concerning Two New Sciences, he notes that a ball rolling down a uniform incline accelerates uniformly. Unfortunately, the most accurate tool to available to Galileo was a water clock, and this experiment has been designed to confirm his results using more-precise measurements from a motion detector and computer software. Similar to previous experiments, a test-cart was observed in motion down an incline track and using the Logger Pro software, precise graphical representations were created. Data Table for […]
Introduction: Isaac Newton’s Third Law of physics states that for every action there is an equal and opposite reaction. This principle describes interactions between bodies, and an experiment has been conducted to study these relations. In the following, two Force Sensors were utilized in connection with computer software to observe and generate graphical data for such interactions. Analysis: (1) Examine the two data runs. What can you conclude about the two forces? How are the magnitudes related? How are the signs […]
