See how Kuest teaches it

It asks before it tells, so you do the thinking and it sticks.

You: A car speeds up evenly from 0 to 20 m/s in 5 seconds. How far does it travel?
Kuest: Distance is speed times time, but the speed is changing here. What speed would you use?
You: 20 m/s for 5 seconds, so 100 m.
Kuest: That would be true if the car went 20 m/s the whole time. It started at 0. If it speeds up evenly, what's its average speed?
You: Halfway between 0 and 20, so 10 m/s. 10 × 5 = 50 m.
Kuest: 50 m. You can check with d = ½at²: a = 20 ÷ 5 = 4 m/s², so ½ · 4 · 5² = 50 m.

With steady acceleration, use the average speed (or d = ½at² from rest), not the final speed.

The method

How to study Physics with Kuest

Physics clicks when you can explain what's happening before you pick an equation. Draw the situation, reason about it out loud, then solve many varied problems so you learn which idea each one needs.

  1. Reason about the situation firstTutor chat

    Kuest asks what's moving, what forces act and what stays constant before any formula, so you choose equations for a reason.

  2. See it drawn and simulatedTeaching board

    The teaching board draws free-body diagrams and runs simple simulations like a projectile or a pendulum, so you can see the motion.

  3. Graph motionGraphs

    Plot position, velocity and acceleration over time and read slopes and areas the way AP questions expect.

  4. Talk through a problemVoice tutor

    Explain your approach out loud with the voice tutor, which asks follow-up questions that catch a wrong assumption early.

  5. Practice varied problemsQuizzes

    Mix kinematics, forces and energy questions so you get used to deciding which principle applies.

  6. Take a timed mock examMock exams

    Sit a practice test with free-response questions that ask you to justify your reasoning, then review every miss.
