Purpose Determine the acceleration in a quick sprint. Question What would the participant’s acceleration be if he/she sprints forward in a positive direction? Hypothesis/Prediction When a person sprints forward‚ it means he/she speeds up. Consequently‚ the acceleration should be positive. When the velocity accelerates at a constant rate‚ the acceleration should remain constant. Therefore‚ if the participant is moving toward a positive direction and the speed increases‚ then the acceleration

Solving Part A: Center of Mass in One Direction 1. Since the mass of the plate is a uniform‚ the center of mass is in the center of the plate. The plate has diameter d = 28 cm‚ thus the center of mass is 14 cm from the edge of the plate. In the lab‚ two scenarios will be analyzed; 1) when the glass is standing up‚ and 2) when the glass is laying on its side. When the glass is standing up‚ its mass is uniform about the axis of symmetry. Therefore‚ the horizontal center of mass will be at the exact

Processing Raw Data: Conclusion: It is hypothesized that the tension found in the string based on the mass of the washers would be equal to the tension derived from the formula for centripetal force‚ because it is the same string and therefore the same tension. Our findings supported this as the centripetal force formula gave us a tension that is very close to the tension found through the mass of the washers when you account for errors in measuring. The forces must have been equal‚ or the

Alcohol Lab Data Conclusion Objective: The objective of this lab was to find the concentration of an unknown alcohol solution. Procedure and Data: We found the masses of 10.00 mL of each of the known concentrations of alcohol (minus the beaker mass) by placing the beaker onto the scale‚ zeroing the scale‚ and then pouring alcohol into the beaker‚ repeating for each different concentration solution. Then‚ using the same method‚ we found the mass of 10.00 mL of the unknown concentration. We recorded

Resolution of Vectors Equilibrium of a Particle Overview When a set of forces act on an object in such a way that the lines of action of the forces pass through a common point‚ the forces are described as concurrent forces. When these forces lie in the same geometric plane‚ the forces are also described as coplanar forces. A single G G equivalent force known as the resultant force FR may replace a set of concurrent forces F1 and G F2 ‚ as shown. This resultant force is obtained by a process of vector addition

Lab 1 – Measurement of Space and Time Anthony Lucci Lab Partner: Amy Hayes Question 4: Both the height and diameter of the cylinder were taken to find the volume; five times for both measurements. Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting

Acceleration is the rate of change of velocity with time. Velocity is a vector physical quantity; both magnitude and direction are required to define it. the length of an imaginary straight path‚ typically distinct from the path actually travelled by P. Distance is a numerical description of how far apart objects are. In physics or everyday usage‚ distance may refer to a physical length‚ or an estimation Time in physics is defined by its measurement Formula Acceleration= change

December 2011 Vectors Math is everywhere. No matter which way you look at it‚ it’s there. It is especially present in science. Most people don’t notice it‚ they have to look closer to find out what it is really made of. A component in math that is very prominent in science is the vector. What is a vector? A vector is a geometric object that has both a magnitude and a direction. A good example of a vector is wind. 30 MPH north. It has both magnitude‚(in this case speed) and direction. Vectors have specific
