AP Physics 1 Projectile Motion

Which of the following would NOT be considered a projectile? 

• a cannonball thrown straight up
• a cannon ball rolling down a slope
• a cannonball rolling off a table
• a cannonball thrown in the air

The horizontal component of a projectile's velocity is independent of...

• it's range
• time
• the vertical component
• none of these

In the absence of air friction, the vertical component of a projectile's velocity doesn't change as the projectile moves. 

• True
• False
• Sometimes true
• Sometimes false

In the absence of air friction, the horizontal component of a projectile's velocity doesn't change as the projectile moves. 

• True
• False
• Sometimes true
• Sometimes false

A ball is thrown into the air at some angle. At the very top of the ball's path, its velocity is

• entirely vertical
• both vertical and horizontal
• entirely horizontal
• not enough info

In the absence of air resistance, the angle at which a thrown ball will do the farthest is

• 15^o
• 30⁰
• 45^o
• 60⁰

At the instant a ball is thrown horizontally with a large force, an identical ball is dropped from the same height. Which ball hits the ground first? 

• Neither- they hit at the same time
• the horizontally thrown ball
• the dropped ball
• None of these
