What is the acceleration of a projectile on Earth?
What is -9.8 m/s^2?
The initial horizontal velocity (vi in the x-direction) for a ball thrown horizontally off a cliff is 40 m/s. The ball stays in the air for 3 seconds. How far from the base of the cliff does it land?
What is 120 m?
This is the building block of matter
What is an atom?
The distance a projectile travels in the x direction
What is range?
Because motion in the x-direction and the y-direction are independent of one another, the amount of time a projectile is in the air depends on ...
What is gravity? (Will also accept "Y direction")
A physics student stands with his paintball gun and fires it off horizontally. The paintball leaves the gun from a height of 1 m and lands on the ground 36.0 m away. How fast did the student shoot the ball?
Pressure describes what physical quantity spread out over a certain area?
What is force?

What is 5.1 m?
This is the first element on the periodic table
What is hydrogen?
This velocity stays the same while a projectile flies through the air
What is horizontal velocity?
When are you able to use this equation? v=d/t
What is when there is no acceleration
A baseball is thrown horizontally off of a cliff with an initial velocity of 80 m/s. A bowling ball is dropped from the same cliff at the same time. Which hits the ground first?
What is both hit at the same time?
This is the name for the drag force on a projectile
