However, we can translate these words into mathematical expressions called kinematic equations. This is the long and short of the theoretical part of kinematics, and basically all there is to it. Even a textbook on the table could be an example of kinematics if you consider the vibration of atoms and molecules. Practically any object in existence involves kinematics as long as it's moving. Say: Kinematics is shooting a basketball, water running down from a waterfall, a moving train. Kinetics considers why the motion happens, and kinematics is concerned with how it happens.īecause kinematics involves a substantial amount of math, we must grasp the basic concepts and terms first to better understand why we are performing the math that we are. A good idea is to think of it as the how and the why. Today, we're discussing kinematics, the science dedicated to an object or substance in motion without considering the forces that stimulate it. However, kinetics is the study of the forces that affect or cause motion (Newton's Laws), such as the way friction affects walking or running or how an enzyme causes changes in a chemical system. Both concepts are branches of motion and are very similar. Kinematics should not be confused with kinetics. In physics, it belongs to a branch called Mechanics. It is generally defined as the study of the motion of points, objects, or groups of objects. Say: Kinematics is derived from the Greek word Kinesis which means movement. Can you tell me what it means? (If someone answers correctly, positively reinforce the answer and continue.) You'll also need:Īsk: Has anyone heard the word "Kinematics" before? (Allow the students to answer.) If yes, great. Prepare projections beforehand that list the kinematic equations and the example. Materials: This lesson is an introductory lesson to the larger concept of kinematics, more of a lecture than an activity. Next Generation Science Standard: Use mathematical representations of phenomena to describe explanations. Lesson Objective: Understanding the meaning of kinematics, real-world examples, elements of kinematics, and intro into describing the movement of objects using numbers and equations.
