Lecture 19 - Force and motion continue. Develop conceptual idea of force and motion. Students first distinguish between moving objects that are under the influence of a force and moving objects that are not under the influence of an unbalanced force. When there are forces acting on an object so that it changes speed or direction, they think about the forces that are affecting the motion. They identify the kinds of forces and explain the relative strength of the forces. They consider how to measure the forces and how to diagram (vectors or free-body) the multiple forces acting on a single object. | Lecture Science 1 - Associate Degree in Education: Lecture 19 - Dr. Arshad Bashir
