Vectors
Have magnitude
Have direction
Have magnitude and direction
Same thing as scalar
Which is not a vector?
Displacement
Time
Velocity
Acceleration
Vectors are parallel if they
have same direction
have opposing directions
When drawing vectors, length matters
True
False
We draw vectors head to head when adding them together
True, yes head to head
False, head to tail
We draw resultants:
Tail of first to head of last
Head of last to tail of first
Head to head
Vectors:
Can be added in any order
Can be multiplied
Do same units
Must describe same physical quantitiy
We can find the resultant by:
using Dillner's Theorem
Only by measuring
using Pythagorean Theorem

In projectile motion, what do we call the highest point an object travels?
Velocity final
Altitude
Zenith
Velocity intiial
In projectile motion, the zenith point has a Velocity in the y direction of:
0
-9.8 m/s/s
equal to the initial velocity
Projectile Motion can be described by how many component vectors?
1
2
3
4
Projectile motion: ax =
0
-9.8
9.8
cat
In projectile Motion, ax=0 because
velocity in x direction is constant
velocity in y direction is constant
gravity
dog
Projectile Motion: gravity affects
vertical direction
horizontal direction
both vertical and horizontal direction
neither vertical or horizontal direction
ay=

horitzontal distance
Vertical distance
Altitude is
horizontal distance
vertical distance
Maximum range is
45 degrees
90 degrees

bullet fired
bullet dropped
both at same time
