What assumption can you make for the initial velocity, in the y-component of projectile motion of an object dropped from a certain height?

• Initial velocity is greater in the y-direction

• Initial velocity is less than 0 m/s

• No initial velocity in the y-direction

• Initial velocity is greater and equal to 0 m/s

What assumption can you make for time in projectile motion of an object launched from a certain height?

T_x​(horizontal) ​ ________ T_y​(vertical)

• Tx>Ty

• Tx<Ty

• Tx≠Ty

• Tx=Ty

If you decrease the height you launch an object, the time the object will be in the air will ​......

• increase

• decrease

• equal to 0

• less than horizontal time

Which statement is not true about projectile motion?

• Horizontal motion and vertical motion of the projectiles are independent but simultaneous.

• Projectiles are object propelled in the air.

• Time covered by the projectile during its motion is equal in both vertical and horizontal directions.

• Air Resistance greatly affects both horizontal and vertical motion of the projectiles.

Acceleration is defined as

• the change in velocity over time

• the change in position over time

• he change in time over velocity

• the change in time over distance
