It doesn't change, this velocity stays the same.
What is horizontal velocity of projectiles?
200
This is the standard unit for vertical displacement

200
This quantity links together the horizontal and vertical velocities.
What is time

Decreasing the gravitational pull (like on the moon) has this effect on a projectile's range.
What is increases the range of a projectile.
300
This is the only force that acts on a projectile.
What is gravity?
300
This quantity is zero for all horizontally-launched projectiles.
You must be very specific for credit.
What is initial velocity in the vertical direction?
300
A ball is shot at a bucket from a table with a height of 25 m. The initial velocity is 4.5 m/s. What is the range of the ball?
What is 9.9 m
300
This is what the path of a projectile is called.
What is the trajectory?
