Projectiles Flashcards
1
Q
Projectiles
A
launched at an angle
both x and y coordinates
2
Q
Acceleration vector always points
A
DOWN
3
Q
Initial velocity
A
-Unlike horizontal projectiles, there is both vix and viy
-We can resolve it using:
Ay= A sin 0
Ax= A cos 0
4
Q
How to solve projectile motion?
A
1) First always use the angle and initial velocity to find vix and viy
2) divide x and y into columns. Make a separate column for Y (Up and down)
5
Q
To maximize the distance, horizontally launch at…
A
45 degrees
6
Q
To maximize the time, horizontally launch at…
A
90 degrees
7
Q
The smaller the angle…
A
the shorter the time
and the farther it will go
