What is range in projectile motion? Formula?

Range is the horizontal distance traveled by the projectile

For any projectile launched on level ground, the final speed is _____ the initial speed.

the same as

Changing the angle has _____ on the final speed relative to the initial speed.

no effect

More vertical launch velocity ⇒

higher maximum height ⇒ longer time in the air.
