Also about Automobiles and us how we correspond If you do not have your permit, please provide the last four digits of your social security number so that your teacher can issue your drug and alcohol certificate. My last four digits are: 7527 Module 2: The Driver: Complete one option below. OPTION 1: Aha Moments: Aha moments are times when you have been reading something and the text suddenly makes sense or becomes clear to you.
A good example of continuity is an infinite graph, i.e, a never-ending sequence. f. Discrete: The definition of discrete means that data can only take on certain values. For example, if someone is taking a poll of the number of students in a class, the data has to consist of whole numbers (you cannot have half of a person). 15. Following are the speeds of 40 cars clocked by radar on a particular road in a 35-mph zone on a particular afternoon: 30, 36, 42, 36, 30, 52, 36, 34, 36, 33, 30, 32, 35, 32, 37, 34, 36, 31, 35, 20
Average Speed of Box-Cars This lab of the Box-cars recorded the average speed of a box-car going down a wooden plank that measured at 1.22 yards long was declined. The Box car started with a zero velocity and the boxcar was let go by one of the group members, then the object started to roll down the flat plank and it increased in speed and velocity, giving our group different speed times. II. Problem Hypothesis: If the boxcar was let go, its speed will gradually change, but also the way of rolling could raise the speed to a higher Velocity. Procedures: Gather up the following materials: 1 Blue cart, 1 wood plank, 1 stop watch and 1 meter stick.
In the study by Loftus and Palmer on eyewitness testimony, the subjects gave different estimates of the speed of the cars depending on how the question was asked. Give two explanations for this. [4] 3. The following table appears in the study by Loftus and Palmer on eyewitness testimony. Give two conclusions that can be drawn from this table.
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.
2. “A body at rest will remain at rest unless acted upon by an outside force.” Example- A car accelerates from a stop sign or a stopped car is propelled forward by a rear –end collision. Conservation of Energy The law of conservation of energy states, “Energy can neither be created nor destroyed. It can only be changed from one form to another.” Example- If a car slows down gradually; the brakes develop friction and heat. During an auto crash, the transfer of energy happens at a much greater rate into different forms.
The Buggy Lab Group 5: Jonathan, Emma, George Purpose: To determine the graphical relationship and mathematical relationship between the position of the buggy moving at a constant velocity (DV) and the time it travels (IV.) : The position of the buggy moving at a constant velocity (DV) & the time it travels (IV) Factors in Lab: (Factor- variable that affects the lab) * constant velocity (speed) * on & off switch * distance * time (stopwatches) Materials: 1) ruler (meter stick) 2) nuts 3) buggy 4) stopwatch Apparatus: Jobs: 1) Timer (person with stopwatch and telling the runner when to place nut behind car) 2) Runner (person placing nuts behind buggy) 3) Straightener ( person keeping car in a straight line) Procedure: 1) Assign tasks 2) Pick & Start starting point (origin) 3) Start car 4) Time started when back of car reaches origin 5) Timer says “mark” 6) Runner places mark where back of car was 7) Continue for 6 data points 8) Count tiles 9) Measure partial tile 10) Repeat steps 8 & 9 for all 6 data points Raw Data (slow car) Time(sec) | Position(m) | 4 | 0.57 | 8 | 1.36 | 12 | 2.20 | 16 | 2.95 | 20 | 3.77 | 24 | 4.52 | Fast Car Time(sec) | Position(m) | 4 | 2.19 | 8 | 3.66 | 12 | 5.74 | 16 | 6.93 | 20 | 9.26 |
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.
I. Do you ever pull into a parking spot and see someone else pull in next to you but wait in your car to make sure they don’t scratch yours. I do it all the time. II. There are many ways to remove scratches from your vehicle.
When the car stops and reverses, a negative constant velocity is being represented. This is, again, because it is traveling at a constant direction. The only difference is that it is traveling in the negative direction. Finally, the car shows deceleration at two time intervals. The first being when the car begins to slow down to a stop when it reaches the left side of the road.
