What is the horizontal velocity of any projectile?
100
This is another word for the vertical distance traveled by a projectile.
What is height?
100
This is the value for gravitational acceleration on Earth.
What is 9.8m/s^2?
200
meters (m)
What is distance?
200
x
What is horizontal distance or range?
200
This is what you get when you multiply initial horizontal velocity by the amount of time a projectile is in the air. (vxo*t)
What is range (or horizontal distance)?
200
This force causes the acceleration of a projectile.
What is gravity?
200
This is in the shape of a parabola.
What is a trajectory?
300
meters per second (m/s)
What is velocity?
300
y
What is vertical distance or height?
300
There are none of these at work on a projectile, which is why its horizontal velocity doesn't change.
What are forces?
300
This is always zero for a horizontally-launched projectile.
What is initial vertical velocity?
300
This is an object upon which gravity is the only acting net force.
What is a projectile?
400
meters per second per second (m/s/s or m/s^2)
What is acceleration?
400
g or ag
What is gravitational acceleration or 9.8m/s^2?
400
A car traveling at a speed of 50 m/s drives straight off of a cliff. If the cliff is 40 m high, the distance away from the cliff that the car will land is this.
What is 143 meters?
400
A ball tossed vertically upward rises, reaches its highest point, and then falls back to its starting point. This is always the direction of its acceleration.
What is downward?
400
This is the distance a projectile lands from its launch point.
What is range?
500
Newtons
What is force?
500
vy0
What is initial vertical velocity?
500
A water balloon is launched horizontally at a height of 1.5 meters above the ground. Its launch speed is 30 m/s. The instant before the balloon hits the ground, its horizontal speed is this.
What is 30 m/s?
500
Pudge Rodriguez hits a pop fly that goes straight up. The ball leaves the bat with an initial speed of 20 m/s and takes 2 s to reach its maximum height. This is the maximum height the ball reaches.
What is 20 meters?
500
In order to more easily understand the motion of a projectile, we break its motion down into these parts.
