Introduction
Lab 7 deals with Conservation of Energy which means that the energy can neither be created nor
lost. If there is no external force acting on the system the E before = E after and can be
represented by the equation below:
Ebefore = Eafter
E=K+
Torque

Introduction
In this experiment, the concept of torque was analyzed. In physics, torque is the force that is
applied to a body about its axis of rotation or pivot. Mathematically, the magnitude of torque is
the cross product between the applied f
Torque
Introduction
In lab 11, the group tested the concept of torque. The definition of force is a force applied on a
body about its axis of rotation. The rotation can also be explained as a pivot. For this lab, the
torque is calculated by cross product

Introduction
George Atwood, a famous mathematician invented the Atwood Machine in 1784 in order to
calculate force and tension, prove that objects moved under constant acceleration and verify their
laws of motion when under that constant acceleration. T
Introduction
Atwood's machine was built to calculate force and tension which then will be used to prove that
the objects had same constant acceleration no matter the weight. Atwood's machine is a string
holding two masses on each end attached to a pulley
Measured Mass Values in (Kg):
Hanger = 0.005 Kg
Cork Cart = 0.0905 Kg
Plastic Cart = 0.0923 Kg
Felt Cart = 0.0826 Kg
Question 1 Part A:
Cork Cart Data Table:
Description: Cork has a high friction surface. Unlike plastic it is not glossy or soft like felt.
Angular Momentum Lab
Question 1 Part A: Using the parallel axis theorem, write down the equations for the moemnt of

Question 1 Part A:
By looking at the equation:
Where m1 = mass of the cart and m2 = mass of the hanger weight. vi = final velocity, vf = final
