What is the GUESS method in AP Physics 1?

The GUESS method is a systematic approach to solving word problems on the AP Physics 1 exam, one that is accepted by the College Board when demonstrated in written responses due to its logical flow.

Here is what it stands for:

Given

Unknown(s)

Equation(s)

Substitute

Solve

Here is an example of a simple problem solved using this method:

A bicycle rider travels 22 km in 3.25 hours. What is the average speed of the ride in km/hr? In m/s?

G: d = 22 km; t = 3.25 hours

U: speed = ?

E: speed = d/t

S & S: 22 km / 3.25 hours = 6.8 km/hour; 6.8 km/hr (1 hr/60 min)(1000 m / 1 km) = 1.9 m/s
