100

What do the G and U in GUESS stand for?

Givens and Unknowns (your first step in tackling problems!)

200

What do you Solve (the first S) your equation for?

The unknown! (get the Unknown alone!)

300

Anytime you do algebra to get a variable alone, what order do you follow?

SADMEP (reverse PEMDAS)

400

v = v_i + at

Solve this equation for time.

  v - vi

----------   =      t

     a

500

Δx = v_it + (1/2)at²

Solve this equation for acceleration.

2(Δx - v_it)

-------------    =    a

       t²

Identify and Rearrange the Equation (algebra)

100

A car moves 158m forwards before reversing and traveling for 682m backwards. What is the car's displacement?

Δx = x_f - x_i

200

A jet flies 2600 miles in 5 hours. What is its average velocity?

v = Δx / Δt

300

A car starts at rest, and accelerates until it reaches a velocity of 18.6 m/s. If this takes 8 seconds, what was the acceleration of the car?

a = Δv / Δt 

400

A car with a velocity of 12.8 m/s travels for 500 seconds. How far does it travel? 

v * Δt = Δx

or

Δx = Δt * v

500

An object is moving along with a velocity of 3.66 m/s. It accelerates at 0.9 m/s² until it reaches a velocity of 10.12 m/s. How long did this take?

Which equation would you use to solve this problem?

Δt = Δv / a
