Chapter 2.2
Two dimensional kinematics and projectile motion
What You'll Learn
Break two-dimensional projectile motion into horizontal and vertical components
Apply kinematic equations separately to each dimension to solve projectile problems
Identify special cases like level range where vertical displacement is zero
Calculate time of flight, maximum height, and range for projectiles
Use trigonometry to decompose initial velocity vectors into x and y components
Recognize that horizontal velocity remains constant while vertical motion is affected by gravity
What You'll Practice
1
Breaking initial velocity vectors into horizontal and vertical components using trigonometry
2
Finding time of flight, maximum height, and range using kinematic equations
3
