2 Basic principles of Kinetics are the “law of inertia” and the “law of energy.” Sir Isaac Newton “The law of inertia” also known as Newton’s 1st law helps explain what happens during blunt trauma. 1. “A body in motion will remain in motion unless acted upon by an outside force.” Example- 2 cars moving at 55 mph, 1 car stops at the red light, car 2 crashes into a wall. An outside force stops the motion of both cars with very different results. 2.
2) List as many aerodynamic features fitted to the V8 Supercars in order to provide a balance between down force and performance.---Cars use spoilers and wings, a front air damp and side skirts all either made in house by the teams or bought from a specialist company. Each piece is tested and measured by running the car up to a set speed and then allowing the car to stop under friction. This will allow an accurate measure of the aerodynamic drag over a range of speeds. The spoilers are aerodynamic devices designed to diminish unfavourable air movement across the vehicle. Spoilers on the front of the vehicle are usually called air dams, since in addition to directing air flow they also reduce the amount of air flowing underneath the vehicle which reduces lift and drag.
Second Law of Motion: The Validated Truth Purpose: The validation of Newton’s second law of motion, stating that ___________ is the goal of the experiment. This will be done by variations to both the accelerating force and the mass of the car. Materials: |[pic]Low friction cart |Low friction track |Pulley | |string |motion sensor |lab quest system | |weight hanger |measured weights |triple beam balance | Procedure: 1. Begin by placing the track on level horizontal surface. 2.
Brakes. The Racecar brakes are cockpit adjustable bias, ‘spec’ calipers, steel discs. b. Chassis. The Racecar has a steel tube frame. c. Dry Weight.
Impulse and Momentum in Collisions Siven Hang 04 April 2014 Partners: Phil Dubay, Avadhish Dewel Instructor: Yao Hao Objective: The purpose of this lab activity was to study and elastic and inelastic collision and to measure the change in momentum during the collision and the integral of the force over the time of the collision. This lab also helps to investigate how the momentum of an objects change during collisions. Introduction: The theory used in the experiment was Newton’s second law of motion. The theory related the external force on an object to its change in momentum. The equation used in the experiment was ∫F dt=∫dp=mvf-mvi The left side of the equation is the integral of force over a period of time and the right side being the change in momentum of the object.
Carburetor vs Fuel Injection A comparative/ contrast essay by Tony Mizzell In the “automotive performance” industry a question that is often asked is what are the benefits vs downfalls, when it comes to building an engine that uses a carburetor or fuel injection. They both have good as well as bad points. I am going to describe the ways that each provide fuel in an automobile engine. The Carburetor supplies fuel to the gasoline engine by means of vacuum gravity and a manual lever and diaphragm type pump. The fuel is sent under low pressure via a low volume low pressure pump, either electric or mechanical.
Initial velocity of the car b. Displacement of the car in 10sec c. Displacement of the car in first 5seconds and last 5seconds. 2. A 4.4kg block is attached to a 0.6kg block by a cord passing over a smooth pulley as shown in the figure below. [pic] a. If the friction between the block and bench is negligible, calculate i.
It is then divided into two different categories; static friction and kinetic friction. Static friction deals with non-moving surfaces, while kinetic friction deals with moving surfaces. Fluid friction describes the friction between layers within a viscous fluid that are moving relative to each other. Contrary to the belief of most people, fluid friction is the friction that is involved in driving a car, since the molecules in the air are technically a fluid. Lubricated friction is a type of fluid friction where a fluid separates two solid surfaces.
Informative Presentation Outline G.P. – To inform S.P.S. – To inform my audience of the five parts to replace when doing a tune-up on a car. (Object) C.T. – The five parts to replace when doing a tune-up on a car are the spark plugs, spark plug wires, the distributor cap, ignition rotor, and fuel filter.
Compare the acceleration measured for motion up the incline with the acceleration measured for motion down the incline. How does the measured acceleration depend on the mass of the cart? © 2009 PASCO scientific and University of Rochester p. 1 of 10 Physics 141, Lab 1, Experiment 2 Student Workbook PART I: Computer Setup 1. Make sure that the ScienceWorkshop interface is connected to the computer and turned on (look for the green light on the front panel of the interface). 2.
