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. |
