Calibration of Micropipette and Peristaltic Pump By: Andrew Tam Part 1 – Calibration of Micropipette Results and Discussion: We took a micropipette and pipetted out water of volumes 100, 250, 500, 750, and 1000 uL at specific temperatures (for our experiment, our temperature was 22.9oC) and recorded the mass of the water that was ejected from the micropipette in five trials for each setting. We then convert this value back into uL in order to compare the amount delivered […]
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 […]
Written by Arturo I. ABSTRACT For experiment 13 Ballistic Pendulum, we used the conservation of momentum and mechanical energy to determine the velocity of a ball as it is shot from a launcher. The angle was measured every time the launcher was released for method A. For method B, we removed the pendulum bob and shot the ball off the table onto the floor, where we recorded the distance of the x axis from the table to the spot where […]
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 […]
