April 29‚ 2014 Abstract The objective project was to use our knowledge of physic properties to create a working car that was powered by a mouse trap. I found that the lighter the car was and the more traction the car had‚ the further it travelled. Introduction The purpose of this project was to create a car that is powered by a mouse trap. We were to use our knowledge of physics laws to make the best car we can. I knew from Newton’s Law‚ F=ma‚ that if my car had a lower

The lesson is divided into 3 labs that can be completed in any order. After labs have been completed‚ facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton’s Laws of Motion LAB 1: How fast can it go? Put one car at the top of the ramp and let it roll down. Use a stopwatch to record the time the car rolled. Use this information to calculate the acceleration of the car. Measure the distance the car rolled using the

necessary to produce a temperature change of 1°C per gram of substance. The specific heats of different substances vary‚ and therefore this quantity may be useful in identifying an unknown. The measurement of heat changes is called calorimetry. In this lab activity‚ calorimetry will be used to determine the specific heat of an unknown metal. This will be done by using a styrofoam cup calorimeter containing water. A calorimeter is insulated so as to minimize any loss of energy to the surroundings. Therefore

AIM: Finding the gravitational field strength by using a simple harmonic motion of a spring and slotted masses. INTRODUCTION: When a mass suspended from a spring is displaced‚ due to the acceleration‚ kg s-2‚ from its equilibrium and released it will oscillate up and down with a kind of motion called simple harmonic motion‚ shm. The period (T)‚ time taken to measure for one complete oscillation‚ of this motion is: m/kg =

LAB WRITE- UP NAME: MANOUCHEKA FIDEL DATE: 9/19/14 TITLE: BACK AND FOURTH MOTION PURPOSE (Introduction): To qualitatively analyze the motion of objects that move back and forth. Then analyze and interpret back and forth motion in kinematics graphs. Use kinematic graphs to catalog objects that exhibit similar motion. PRELIMINARY QUESTIONS: Finding the average velocity Do any of the four objects listed above move in similar ways? If so

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
