After watching the video,
what can you say about projectile motion? Projectile motion
Projectile motion Horizontal and Vertical Horizontal and Vertical directions are independent. Horizontal motion has constant velocity.
Vertical motion is freefall motion. Divide and conquer!
Divide and conquer!
Horizontal Vertical Time crosses the line! Horizontal initial velocity
