Term
| In the absence of air resistance, why does the horizontal component of velocity for a projectile remain constant while the vertical component changes? |
|
Definition
| Because the horizontal component has no forces while the vertical component has a force of gravity that increases the directions. |
|
|
Term
| How does the downward component of the motion of a projectile compare with the motion of free fall? |
|
Definition
| They are equal (The vertical component of velocity is the same as freefall.) |

Term
| What do you do with the x=vx times T formula on a vertical problem? |
|
Definition
| Divide each side by T. So eventually you will be dividing your x over your t to get your answer. |

Term
| how do you solve a problem w/o the y? |
|
Definition
| first divide vx by x=vx+t so you have x over vx. Divide that then with your answer use the formula y=1/2gt^2 |
