Projectile Motion

The more mass an object has, the faster it will fall.

• True
• False

If you throw a baseball straight up, what is its velocity at the highest point?

• 9.8 m/s²
• 9.8 m/s
• 0 m/s²
• 0 m/s

• 9.8 m/s²
• 9.8 m/s
• 0 m/s²
• 0 m/s

What is the horizontal acceleration of a projectile?

• 0 m/s²

An object is projected horizontally from a cliff.  The time it takes to hit the ground is

• more than if it was just dropped
• less than if it was just dropped
• the same amount of time than if it was just dropped
• impossible to determine

As an object travels through the air, its vertical velocity 

• changes continuously
• remains the same

When a ball is projected horizontally, what is its initial vertical velocity?

• 10
• 0
• not enough information given

If a bullet is horizontally shot at the same moment another bullet is dropped from the same height, which will hit the ground first?

• Shot Bullet
• Dropped Bullet
• Hit at Same Time

In a projectile motion we always have...

• 1 component (x)

• 3 components (x,y, and z)

• 2 components (x and y)

• 0 components
