Term
the horizontal distance a projectile will travel 

Definition


Term
Where should the center of mass be located at for a rocket to fly straight up? 

Definition
Toward the front of the rocket 


Term
How does the horizontal component of a projectile’s velocity affect the vertical component of a projectile’s velocity? 

Definition
They do not effect each other 


Term
If I were to throw a ball up into the air, when it reaches the top of it’s path, as it is starting to fall, what would be it’s acceleration? 

Definition
9.8m/s^2. (the velocity would be zero) 


Term
I launched a projectile horizontally, with a velocity of 5 m/s and it hit the ground in 1 second. If I increased the horizontal velocity to 7 m/s would it hit the ground sooner, at the same time or later. Explain your answer. 

Definition
It would hit at the same time. The horizontal velocity does not affect the vertical motion 


Term
A ball is thrown into the air at an angle of 50 degrees above the horizontal. It lands on a target that is at the same level as where the ball started. What other angle, if any would the ball have to be thrown toward to hit the same target? 

Definition
40 degrees would produce the same horizontal range. 


Term
If a projectile travels 20 meters horizontally in the first second, how far will it move horizontally in the next second? 

Definition
It will move 20 meters during the next second because the horizontal velocity remains constant. 


Term
What launch angle would provide the furthest range? and why 

Definition
45 degrees, the horizontal and vertical components of the velocity would be equal 


Term
Why does the vertical component of a projectile change throughout its flight? 

Definition
Because of the force of gravity.
