KINEMATICS REVIEW LESSON EXAMPLE 1: Consider the velocity vs. time graph below. The motion of five different people (A‚ B‚ C‚ D‚ and E) are shown on the graph. Study the graph and answer the following questions. Some questions may have more than or less than one answer. Question: 1. Which person(s) changes direction during the time of motion? 2. Which person(s) is/are not moving? 3. Which person has the greatest average speed? 4. Which person(s) has/have a constant‚ positive acceleration

Objective: To study the relationships between position‚ velocity‚ and time‚ with acceleration held constant‚ of an object moving in one-dimensional motion with minimum friction. A motion sensor will be used to measure various aspects of vector quantities. Description: An Air Track is positioned along the edge of the table. It is a long straight metal beam with many small holes that are roughly each 2mm in diameter. It is positioned at an angle to allow the gliders to glide down the slope

Last week‚ my group and I were constructing the roller coaster. I contributed by installing my funnel into the coaster. I did this by making adjusting the track so that it would lead the marble to the border of the tube. I did this because learned that when the marble spins around the edge of the tube‚ it increases the time which was what we wanted. After adjusting‚ I put supports on the funnel that would help the funnel maintain its shape to have the most maximum time possible. I also contributed

will have a curve showing increasing speed or in other words‚ increasing velocity over time. Therefore‚ the results shown in the velocity vs. time graph will have a positive linear slope. The acceleration vs. time graph will then have no slope and just a straight line because the change of velocity is relatively constant. In conclusion‚ when the mass of the weight increases‚ the acceleration won’t and only the speed and velocity over time will change. Materials -Laptop computer -Smart pulley -Retort

PHY 1103 Physics I RKMC - HCT Learning Outcome 1: Sub-outcome 1: Assign given basic units to their corresponding physical quantities. All engineers must use the same language in their communications‚ and one of these universal communication tools is the units of measurements. Physical quantities such as length‚ weight‚ time‚ speed‚ force‚ and mass are measured with standard units. Therefore the magnitude if a physical quantity is given by a number and standard unit of measurement
