an object moves at a constant speed along a circular path. Velocity is always tangent to the path in circular motion. Speed is constant‚ velocity is not. Centripetal Acceleration‚ – acceleration that maintains the object along a circular path directed towards the center. Also called as radial acceleration. In 1673‚ Christian Huygens‚ determined the following relationships. Velocity‚ Where‚ r = radius of curvature/path‚ t = time/period. Frequency (f) – number

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

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

of motion that consists of horizontal and vertical motions which are independent from each other‚ known as vector components. For an object to be considered a projectile‚ it must not be self-propelled. Projectiles move horizontally at a constant velocity. However‚ they undergo uniform acceleration in the vertical direction‚ which is caused by gravity. An important aspect of projectile motion is that the time it takes for the object to travel on the Y axis is exactly the same as the time it takes

Experimental Design: The purpose behind this experiment was to determine the initial velocity of a projectile. Projection motion consists of kinematics of motion in the x and y directions. With two dimension kinematics‚ there are the x and y components in any given velocity. In projectile

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
