Which hits the ground first if they start at the same height: a dropped ball or a ball launched with a

horizontal velocity?

• the dropped ball

• they both hit at the same time

The path followed by a projectile is also known as its

• trajectory

• range

• height

• vertical displacement

The horizontal velocity of a projectile dropped from a moving object is the___________ as the velocity of the

moving object.

• 0 m/s

• same

• greater than

• less than but not 0 m/s

Which of the following statements about the horizontal and vertical components of projectile motion is true?

• Changes in the horizontal component occur only when the vertical component changes.

• Both the horizontal and vertical components are always constant.

• The vertical component changes while the horizontal component stays the same.

• The horizontal and vertical components are dependent of each other.

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
