Kinematic Variables
What is a placeholder or symbol that holds a value that can change or vary depending on the context
What is a variable?
What is the number of kinematics formulas we use in this class?
4
What is the FIRST thing you do when solving a kinematics problem like a physicist?
Rewrite the problem in your own words (write the problem number!)
What is the variable that represents a change in position or Displacement?
Delta X
What is the kinematic formula that does not involve Displacement?
Vf = Vi + at
When is it okay to not pull out the variables?
NEVER ALWAYS PULL OUT THE VARIABLES
What is the variable that represents acceleration?
a
What is the kinematic formula that does not involve acceleration?
Δ x = 1/2(Vi + Vf)t
After you pull out your variables what is the next step in solving a kinematics problem?
What are the variables that represent initial and final velocity?
Vi and Vf
What is the kinematic formula that does not involve Vf?
Δ x = Vit + (1/2)at^2
What is the variable that represents time?
t
What is the kinematic formula that does not involve t?
Vf^2 = Vi^2 + 2aΔ x
Why do I have to solve like a physicist even if I can solve the problem in my head?
