2-D Kinematics

Drop-Shoot predictions Clicker questions about the drop-shoot demonstration Do this AFTER talking about components, and why we split things into X & Y Independence of X & Y vectors

One ball is dropped. The other is shot horizontally simultaneously. Which hits the ground first? 1.Dropped ball 2.Horizontally shot ball 3.Both at the same time

One ball is dropped. The other is shot horizontally simultaneously. Which has larger vertical- component to its velocity at the end when they hit? 1.Dropped ball 2.Horizontally shot ball 3.Both are the same time

Projectile firing across flat ground Several clicker questions to be done BEFORE the projectile launcher demo Do these AFTER drop-shoot demo and 1- 2 numerical questions (3.24 & handout #1)

Which object has a faster horizontal component to velocity? All have the same TOTAL speed. 1.Object launched at 30 degrees 2.Object launched at 45 degrees 3.Object launched at 60 degrees

Which object spends more time in the air when flying over FLAT ground? All have the same TOTAL speed. 1.Object launched at 30 degrees 2.Object launched at 45 degrees 3.Object launched at 60 degrees

When firing a projectile across FLAT ground, the projectile will go furthest if launched at an angle: 1.0-30 degrees 2.30-60 degrees 3.60-90 degrees

Launch projectile over FLAT ground 15 degrees 30 degrees 40 degrees 45 degrees Show the next few Clicker questions before 50, 60, 75 degrees.

Which goes further? 1.Object launched at 30 degrees 2.Object launched at 60 degrees 3.Both go the same distance

Firing projectiles across NOT-FLAT ground Clicker questions upcoming

When firing a projectile down a hill, the projectile will go furthest if launched at an angle: 1.Greater than 45 degrees 2.Equal to 45 degrees 3.Less than 45 degrees

When firing a projectile up a hill, the projectile will go furthest if launched at an angle: 1.Greater than 45 degrees 2.Equal to 45 degrees 3.Less than 45 degrees

Hunter-Monkey demo Clicker question predictions

Where will the bullet go? 1.Above the monkey 2.Below the monkey 3.Hit the monkey

Bullet fired much faster. What will it do? 12345 1.Above monkey 2.Below monkey 3.Hit the monkey

Bullet fired much slower. What will it do? 12345 1.Above monkey 2.Below monkey 3.Hit the monkey
