The aim here is to understand and explain the parabolic motion of a thrown object, known as projectile motion. Motion in one direction is unrelated to motion in other perpendicular directions. Once the object has been thrown, the only acceleration is in the y (up/down) direction due to gravity. The x (right/left) direction velocity remains unchanged (neglecting air resistance).
Explains the basic concepts of projectile motion and how they fit into example problems.
Basics of projectile motion. Requires knowledge that the x-component of the velocity does not change.
A list of student-submitted discussion questions for Projectile Motion Concepts.
Discover how to hit a tennis ball to get it to land anywhere you want.
Try to hit a target by controlling the x and y velocity with which a cannon shoots.
A review of the terms distance, displacement, velocity, speed, and acceleration. Also looks at graphs of motion, using the kinematic equations, projectile motion, and free fall.
