Physics 121 Week 2 Question and
answers verified to pass 2025
1st kinematic equation: - correct answer ✔constant velocity equation
X: xf=xi+Vx🔺t
Y: yf=yi+Vy🔺t


Equation for acceleration - correct answer ✔🔺V/🔺t


2nd kinematic equation - correct answer ✔When velocity is not constant (Vx
or Vy are changing)
X: Vxf=Vxi+Ax🔺t
Y: Vyf=Vyi+Ay🔺t


3rd Kinematic Equation: - correct answer ✔X: 🔺X=Vix🔺t+(1/2)Ax(🔺t)^2
Y: 🔺Y=Viy🔺t+(1/2)Ay(🔺t)^2


4th Kinematic Equation - correct answer ✔X: Vxf^2=Vxi^2+(2)ax🔺x
Y:Vyf^2=Vyi^2+(2)ay🔺y
*remember that when you square a velocity, it takes the way the direction of it.
Take square root of velocity and choose which direction is best, if needed


Slope equation - correct answer ✔rise/run
🔺Vy/🔺t


Area is a change in ____ - correct answer ✔Velocity
