- vo (initial velocity)
- vf (final velocity)
- x (displacement)
- a (acceleration)
- t (time)
vf = vo + at
x = vot + 1/2at2
vf2 = vo2 +2ax
The units for speed are m/s.
Just like speed, except it's a vector.
The units of acceleration are m/s2.
Step 1: Write out all five variables in a table. Fill in the known values, and put a "?" next to the unknown values.
Step 2: Count how many known values you have. If you have three or more, move on to Step 3. Find another way to slove the problem (or to get another known variable).
Step 3: Choose the fundamental kinematics equations (slide 2) that contains all three of your known variables. Plug in the known values and solve.
Words From Our Students
"StudyBlue is great for studying. I love the study guides, flashcards, and quizzes. So extremely helpful for all of my classes!"
Alice, Arizona State University
"I'm a student using StudyBlue, and I can 100% say that it helps me so much. Study materials for almost every subject in school are available in StudyBlue. It is so helpful for my education!"
Tim, University of Florida
"StudyBlue provides way more features than other studying apps, and thus allows me to learn very quickly! I actually feel much more comfortable taking my exams after I study with this app. It's amazing!"
Jennifer, Rutgers University
"I love flashcards but carrying around physical flashcards is cumbersome and simply outdated. StudyBlue is exactly what I was looking for!"
