It provides an understanding of the processes by which physicists increase knowledge in their field. Teachers investigate physics through explorations of force and linear motion. | Lecture # 18 SCIENCE 1 ASSOCIATE DEGREE IN EDUCATION FORCE AND MOTION Overview of the Unit This unit builds a foundation for an appreciation for physics as its own scientific discipline. It provides an understanding of the processes by which physicists increase knowledge in their field. Teachers investigate physics through explorations of force and linear motion. Week-wise Plan In the first week, they apply forces and cause linear motion at constant speed and direction. Then they move on to accelerated motion in a straight line. In the second week, the study is expanded to motion that can change in magnitude and direction. The third week of this unit develops and deepens the prospective teacher’s pedagogical content knowledge. They can then successfully introduce young children to appropriate concepts related to force and motion. Teachers focus on the following topics: Motion The laws of motion Concepts of inertia and mass The relationship between action and reaction Force pairs Force and acceleration Areas of Focus You should make an effort to help Student develop an understanding of the distinction among speed, velocity, and acceleration. The unit identifies a variety of forces considered in Science I (for instance, normal force, friction, gravity, net force). Learning outcomes for this unit Student Teachers should be able to: articulate and demonstrate the principles of motion and forces and apply them to examples of interactions between objects investigate the relationships among force, mass, and motion of an object or system conduct investigations to determine the position and direction of a moving object (and represent its motion on a graph) draw free-body diagrams that list all the forces acting on an object and the resulting direction of motion Learning outcomes for this unit continue Student Teachers should be able to: analyse the motion of objects by the classical relationships known as the laws of motion begin to identify the unit’s underlying .
