Dat Truong A-3 Honors Graphical Analysis of Motion Purpose: To determine the relationships between: Displacement versus time graph and velocity. The area under the velocity time graph and displacement. Procedure: Set up the experimental apparatus as shown on the instructors? demonstration table. Release the cart spring. Start clock as car passes first gate and stop clock as car passes second gate 10 cm away. Record data in Raw Data chart. Repeat steps one through three for three trials. Repeat step one through four moving the second gate down the track in 10.0cm increments until the displacement between the gates reaches 50.0cm. Position and Time Raw Data Trial # Initial Position (cm) Final Position (cm) t(sec) 1.0 50cm 60cm .22 2.0 50cm 60cm

Chapter 1-2 (Introduciton and Motion in One Dimension)
x=vt
x=1/2at^2 + Vi(t) (works well with no initial velocity)
Vf^2 = Vi^2 + 2ax
Vf = Vi + at
Average Velocity = (Vf + Vi)/2 (constant acceleration)

Chapter 3 (Vectors and Two-Dimensional Motion)
(Lowercase is a side/length; Uppercase is an angle)
Law of Cosines
a^2 = b^2 + c^2 - 2bcCosA
b^2 = a^2 + c^2 - 2acCosB
c^2 = a^2 + b^2 - 2abCosC
Law of Sines
SinA/a = SinB/b = SinC/c

Chapter 4 (The Laws of Motion)
Newtons 2nd Law: F=ma
Force is measure in Newtons = kg x m/s^2
Force of Weight (weight of object): Fw = mg (mass x acceleration of gravity) *Always to center of Earth*

Chapter 3: Two Dimensional Motion and Vectors (Now the fun really starts) Opening Question I want to go to the library. How do I get there? Things I need to know: How far away is it? In what direction(s) do I need to go? One dimensional motion vs two dimensional motion One dimensional motion: Limited to moving in one dimension (i.e. back and forth or up and down) Two dimensional motion: Able to move in two dimensions (i.e. forward then left then back) Scalars and Vectors Scalar: A physical quantity that has magnitude but no direction Examples: Speed, Distance, Weight, Volume Vector: A physical quantity that has both magnitude and direction Examples: Velocity, Displacement, Acceleration Vectors are represented by symbols Book uses boldface type to indicate vectors

Motion Graphs and Kinematic Equations Lab Billy Andrews (Eric Wright/Paul Pennoyer) 10/16/11 Purpose -To use CPO tracks and photo-gates to collect time data on a moving energy car at varying intervals of distance and then calculate the acceleration, velocity, and position versus time of the energy car. With this data, motion graphs will be created to compare the accuracy of your measurements to the 5 kinematic equations. Procedure: Materials -CPO Tracks -Photogates and Timing Equipment -Energy Car -CPO Track Stands -Calculator -Track Clamps Equations

Arroyo 1 Mikayla Arroyo Period 6 1-26-10 Newton, Bernoulli, or Archimedes Newton?s, Bernoulli?s, and Archimedes? laws and principles are essential to our understanding of life and physics. Such as, when we can throw a ball harder, we make it go further, why objects float or sink, and how a wing of an aircraft or bird helps it fly. Out of the three physics concepts, Newton?s laws are the most important, Bernoulli?s principle is the second most, and then Archimedes? principle
