We used a vernier caliper to obtain the diameter of those two and therefore, the radius. When adding all the numbers together, we found that the true radius(r) of the orbit was 0.139 m. To find our tension, we needed to find out how much weight we needed to pull the object towards away from the spring and on the tip of the pointer as shown below. The tension needed to pull the mass on the tip of the pointer 1.05 kg. In theory the force of acceleration needed to pull the mass to same exact spot should equal the force of tension multiplied by the force due to gravity. Using Newton’s second law, F=ma, we know that the
Because it was not a direct force like pushing or pulling. The force of gravity on an object depends on the mass and the distance. Free fall is caused by this gravitational force. Every object falls down at the same speed because the gravitational acceleration is independent of the mass of the object. Gravitational acceleration was found using this formula: g=2ht2 Impact speed of the falling objects was found using this formula: v=2ht Percentage error between calculated values and those obtained from the slope of the graphs were found using this formula: percent error=calculated value-slopecalculated value x100% PROCEDURE Firstly we placed the falling sphere apparatus on the table.
Oscillations of a Mass - Spring System Determination of “K” by the use of a Spring Oscillations System Experiment #3 for AMS320 involves a spring oscillating system to determine the value of “K”, the force value of an oscillating spring system. The spring is secured to a solid point and allowed to hang vertically below the solid stand. On the bottom of the spring is attached a steel ring with in which to attach a known amount of weight in (kg). The weights are added to the ring and the spring is pulled into a small amount of tension and released. The spring will then oscillate up and down and a stopwatch will be used to measure the amount of time it takes the weight and spring system to stretch and recoil ten times.
Newton’s Law of Motion Newton’s law of motion consists of three physical laws and explains the connection between a mass and a force acting upon it, and its motion in response to that force. 1. “Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it” Newton’s first law of motion is essentially Galileo’s concept of inertia, and is moving object tends to stay in motion, with the same direction and speed. For motion (or lack of motion) to change it requires an unbalanced force acting on it. If you're going in a specific direction, you will always go in that direction unless something happens to you.
Newton’s Second Law and the Work-Kinetic Energy Theorem October 13, 2010 Abstract This experiment utilizes an air track first as an inclined plane with the slider accelerating due to gravity and second as a level surface with the slider accelerating due to the pull of an attached free-falling object of known mass. In both cases, the Work performed is calculated based on formulas for mechanical work and for kinetic energy. The two results are compared. The first part yielded an average acceleration of 0.715 m/s2 (a 1.58% error) and the average result for the Work performed was 0.0204 N*m with only a 0.9% difference. The second part suffered critical errors due to improper data and the results are not significant or useful.

Next, the goal was to collect consistent velocity-time data for the "free fall" of an object (meaning the wooden and brass cylinder), which could be affected by air resistance. The following goal was to understand the meaning of standard deviation and calculate it appropriately, after which a plot of "error bars" would be added to the graph of the velocity graph. The standard deviation was used as the uncertainty estimate for the error bars. The last goal for this experiment was to determine by graphical means whether the acceleration experienced by freely falling object was constant and if so, to calculate the value of constant acceleration. In this experiment the infrared photogates were used to measure the motion of a falling object, and this data was recorded by the Data Studio software.

Theory: 3 Kinematic Measurement of Speed In this experiment the steel ball was moving in two dimensions both horizontally and vertically. Since these two components of motion are independent of one another, two sets of equations are used- one for the balls horizontal motion and one for its vertical motion. For the horizontal component, there are no external forces acting on the ball. Therefore there is no acceleration and the ball moves at a constant velocity. The distance the ball travels in the horizontal direction can be calculated using .
Megan Lankford 10/11/12 Physics Lab: The Ballistics Pendulum and Projectile Motion Introduction/Objective In this lab, our focus was to identify the initial velocity of a metal ball by firing it as a projectile and compare it with the velocity. Also, we had to determine the initial velocity of the ball fired into the ballistics pendulum and its relativity to the initial velocity in which the ball plus pendulum moves after firing. This lab demonstrates the principle of conservation of momentum and projectile motion and how they are relative to each other. Procedure 1 To being our experiment, we had to weigh the metal ball and pendulum to give us our mass and help us determine the before and after effects of the collision. After we had taken all of our measurements we had to decide which setting we were going to fire the ball at.
