Projectile Motion

Ignoring air resistance, a projectile will always have motion that consists of...

• 1 component (x)

• 2 components (x and y)

• 3 components (x, y and z)

• Depends on the situation

How is projectile motion similar to free fall motion? (Choose all that apply)

• Both involve the influence of gravity only.

• They always share the same initial velocity.

• Both have an acceleration of -9.81 m/s².

• The horizontal motion in both cases is accelerating.

In horizontally launched projectile motion, what happens to the horizontal and vertical components of velocity over time?

• Both components of velocity remain constant.

• The horizontal component of velocity remains constant, while the vertical component changes due to gravity.

• The vertical component of velocity remains constant, while the horizontal component changes due to gravity.

• Both components of velocity change due to gravity.

The initial horizontal velocity of a projectile is ____ its final horizontal velocity.

• less than

• equal to

• greater than
