Introduction to the Language of Kinematics Describing Motion with Words Scalars and Vectors Distance and Displacement Speed Velocity Acceleration Kinematics is the science of describing the motion of objects using words‚ diagrams‚ numbers‚ graphs‚ and equations. The goal of any study of kinematics is to develop sophisticated models which serve in describing (and ultimately‚ explaining) the motion of real-world objects. Much of our lives are spent in motion‚ travelling

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

represented in magnitude (scaled) and direction by arrows. velocity mass 10 N displacement speed 5 km VECTORS momentum distance : A distance is simply the length of a journey. displacement : displacement is the distance moved in a given direction. Speed / velocity speed : The speed of an object is the rate at which distance is increasing. velocity : velocity is the rate at which displacement is changing. Velocity should always be quoted with a direction. Average speed

shows that the motion is non uniform. The car is not travelling at a constant velocity as the graph is not a straight line. A straight line graph would indicate that the motion is uniform as the position increase is constant throughout. However‚ the graph of the toy car is a curve that becomes steeper as the time increases. This suggests that the motion increases more and more as time passes‚ showing that the velocity is increased each second. As the car is also moving in the positive direction‚

the graph on the right‚ line one is a line moving at a slower velocity compared to line 2 which is moving at a faster velocity in the same about time. There is a small error in this experiment‚ as you can see in the graph of the right‚ the velocity is not as constant. 5. What is the definition of velocity? Velocity is a vector quantity that has the same direction as the displacement. Displacement per unit time is called Velocity. 6. What did you have to do to

and time. Motion is the action of changing position. The aspects of motion are time‚ position‚ displacement‚ velocity and acceleration. Newton has described objects in motion in balanced and unbalanced state. There is equilibrium to the object with balanced forces that are acting on it. He said that the object will never accelerate if there will be no net force acting on it. Thus‚ the velocity is constant and its acceleration is always zero. In the Second Law of Motion‚ he showed that an object will
