1
New cards

Horizontal motion has no effect on

vertical motion

2
New cards

The only variable that horizontal/vertical have in common

time

3
New cards

When you're NOT given a velocity in any capacity

You have to create horizontal/vertical velocities with trig; from there, you can find the total velocity

4
New cards

You can divide by trigs that have an angle

True

5
New cards

If the projectile lands on the same y-value where it started

The total Δy is 0

6
New cards

When the horizontal/vertical velocity isn't specified, assume the problem is talking about

total(hypotenuse) velocity

7
New cards

Velocity

DIRECTION and Magnitude

8
New cards

Direction of total velocity

"angle" then specify above/below horizontal OR specify cardinals

9
New cards

Finding an angle

Step 1. Set trig equal to parts

Step 2. Isolate θ with inverse trig
