PHYSICS Two-dimensional motion

( Report)

You understand velocity and acceleration well in one-dimension. Now we can explore scenarios that are even more fun. With a little bit of trigonometry (you might want to review your basic trig, especially what sin and cos are), we can think about whether a baseball can clear the "green monster" at Fenway Park.

• Two-dimensional projectile motion
• Horizontally launched projectile
• What is 2D projectile motion?
• Projectile at an angle
• Launching and landing on different elevations
• Total displacement for projectile
• Total final velocity for projectile
• Correction to total final velocity for projectile
• Projectile on an incline
• What are velocity components?
• Unit vectors and engineering notation
• Unit vector notation
• Unit vector notation (part 2)
• Projectile motion with ordered set notation
• Optimal angle for a projectile
• Optimal angle for a projectile part 1: Components of initial velocity
• Optimal angle for a projectile part 2: Hangtime
• Optimal angle for a projectile part 3: Horizontal distance as a function of angle (and speed)
• Optimal angle for a projectile part 4: Finding the optimal angle and distance with a bit of calculus
