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

KINEMATICS 1. An object is moving with uniform accleration. Its velocity after 5 sec is 25m/s and after 8 sec‚it is 34 m/s. Find the distance travelled by this object in 12th second. Ans. 44.5 A particle starts with a velocity of 100 cm/s and moves with –2 cm/s2 acceleration. When its velocity be zero and how far will it have gone? Ans. 50s ‚ 25m m/s. After 7 a time interval ∆t‚ the velocity of the body is reduced by half‚ and after the same time interval‚ the velocity is again reduced by half

it’s vertical velocity accelerates or decelerates due to gravity. Purpose: The purpose of this experiment is to be able to measure the velocity of a ball using two Photogates and computer software for timing‚ apply concepts from two-dimensional kinematics to predict the impact point of a ball in projectile motion and ability to understand trial-to-trial variations in the velocity measurement when calculating the impact point. Materials: Computer plumb bob

2.6.1 Draw a vector diagram to show that the acceleration of a particle moving with uniform speed in a circle is directed toward the centre of the circle. Review of basic kinematics: If the acceleration and velocity of an object are parallel (or anti-parallel) then the object’s speed will increase (decrease). If the acceleration and velocity of an object are perpendicular then only the direction of the velocity will change and the speed (i.e. the magnitude of the velocity) will remain constant.

Physics 1 – Mechanics and Heat Lecture Notes Prepared by: ENGR. HAROLD JAN R. TERANO‚ ECE Lesson 5 ROTATIONAL KINEMATICS AND DYNAMICS Uniform Circular Motion – 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
