Critical Content/Concept Web Unit Topic: Mechanics: Forces and Motion Conceptual Lens: Grade: Factors that affect motion Unit Overview 10-12th Motion Displacement, velocity, acceleration vectors Kinematic equations Forces Newton’s 1st law (inertia) Newton’s 2nd law (F=ma) Newton’s 3rd law (action/reaction) This unit introduces students to concepts of physics using basic units and problem solving activities. The unit starts by exploring ways to describe motion, the laws of motion (kinematic equations). It then explores the cause of motion, forces, through Newton’s laws to include the concept of momentum. This unit is very fundamental to the course and should be taught with sufficient time and care.
