Projectile Motion is the study of an object's motion when it is launched or thrown into the air and experiences only the force of gravity. The motion is a combination of horizontal and vertical components that move independently of each other. Students will learn to apply kinematic equations and vector principles to solve problems related to projectile motion, including finding the properties, solving problems, and understanding related standards in high school physics. To achieve the learning objectives, students will learn to describe projectile motion, analyze and describe accelerated motion in two dimensions using equations, review addition of vectors, understand the concept of air resistance, and understand that vertical and horizontal motions are independent. Students will be able to break projectile motion into its two independent components, use kinematic equations to analyze horizontal and vertical motions, recombine the components to find the total displacement and velocity, and understand the effects of changes in initial velocity, angle, and air resistance on projectile motion. Teaching tips and demonstrations, as well as worked examples, are provided to support learning. The section covers projectile motion on level ground and the effects of launch angle and initial speed on range. The maximum range is achieved when the angle of launch is 45 degrees in the absence of air resistance. Students can also practice solving projectile motion problems through various online simulations.
