PPT-Unit 2 1 Dimensional Motion

Mechanics the study of how objects move and respond to external forces Kinematics study of motion with no concern for the cause Motion Perceiving motion is instinctive your eyes pay more attention to moving objects . 4 – Introduction to materials, processes and technical skills in art & design . Week 4 Wire Sculpture. Learning Outcomes. List the tools utilised for wire manipulation. Use primary research to help in the creation of a sculpture. III. Unit Conversions . (p.39-41). SI Prefix Conversions. Dimensional Analysis. A. SI Prefix Conversions. 1. Find the difference between the exponents of the two prefixes.. 2. Move the decimal that many places.. Dimensional Analysis. In Chemistry and every-day life you will often need to express a measurement using a different unit than the one that was initially used. . To convert between units we can use . Kinematic Equations. http://. www.aplusphysics.com. /courses/honors/kinematics/. honors_kinematics.html. Unit #2 Kinematics. Objectives and Learning Targets. Use kinematic equations to solve problems for objects moving at a constant acceleration in a straight line and in free fall.. Now it starts to get more . interesting. (and don’t get freaked out by the equations and subscripts). Projectiles – What path do they follow?. http://www.us-inauguration-day-2009.com/human_cannonball.jpg. You and your friends want to have a movie marathon. All three movies last a total of 390 min. How many hours will it take to watch all three movies?. = 6.5. min. How do we get the unit to change to hours?. Week 4 Wire Sculpture. Learning Outcomes. List the tools utilised for wire manipulation. Use primary research to help in the creation of a sculpture. Create a 2 dimensional wire sculpture. Create a 3 dimensional wire sculpture. University of Michigan. Physics Department. Mechanics and Sound . Intro . Labs. Two-Dimensional Collisions. You have now seen the laws of conservation of momentum and energy in action in one-dimensional collisions, and you have begun to explore rotational motion. Now it is time for you to apply these concepts to a two-dimensional situation.. Systems of Units. Section 2.3. Physical Quantity. Unit. Abbreviation. Mass. Kilogram. Gram (CGS). kg. Length. Meter. Centimeter (CGS). m. Time. Second. s. Temperature. Kelvin. K. Amount of substance. Brownian motion. Wiener processes. A process. A process is an event that evolved over time intending to achieve a goal. . Generally the time period is from 0 to T. . During this time, events may be happening at various points along the way that may have an effect on the eventual value of the process. . Solve unit conversion problems.. Use dimensional analysis to convert between metric units.. Determine the meaning of common metric prefixes.. Use dimensional analysis to convert between metric and non-metric units.. Chapter 3 pg. . 81-105. What do you think?. How are measurements such as mass and volume different from measurements such as velocity and acceleration?. How can you add two velocities that are in different directions?. How can we convert units?. Measurements. Every measurement needs to have a value (. number. ) and a unit (. label. ).. Without units, we have no way of knowing what the actual measurement is. Sometimes the units that something is measured in, need to be converted into a comparable unit for a calculation. Homework for Chapter 2. Read Chapter 2. HW 2.A : pp. 57-59: 8,9,12,13,16,17,20,26,34,35,38,39.. HW 2.B: pp. 60-61: 46,47,48,50,52, 58,59,61. ,70,71,72-75,80.. Learning Objectives for Chapter 2. Students will understand the general relationships among position, velocity, and acceleration for the motion of a particle along a straight line so that given a graph of one of the kinematics quantities, position, velocity, or acceleration, as a function of time, they can:.
