WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
Kinematics rules, from your notes
This is a browser-only tool, and that is all it isIt splits the text you paste by rule, and nothing else. WeSolve+ is a different thing entirely: it reads your whole PDF with AI, writes the reasoning behind every question, speaks the chapter back to you, and remembers what you missed so it can return it.

This tool splits the text you paste by rule and returns cards. It cannot solve a problem or read a graph, so it works on the rules and definitions you already wrote down.
The sign convention is yours and it is binding
Nothing in a problem tells you which direction is positive; you decide, and then every quantity in that problem must obey your decision. Most wrong answers in kinematics are arithmetic that was correct under a convention the student silently changed halfway through. Writing the convention down at the top costs five seconds.
Acceleration is not speeding up
It is the rate at which velocity changes, so an object slowing down is accelerating, with a sign opposite to its motion. This is the single most productive misconception to fix in the unit because it is embedded in ordinary English. Questions exploit the gap deliberately and repeatedly.
Three graphs, one motion
Position against time, velocity against time, acceleration against time. Slope moves you down the list and area moves you back up. Once that relationship is automatic, a question that gives you one graph and asks for another becomes mechanical rather than mysterious, and those questions are common.
The top of a throw is the classic trap
Velocity is zero there and acceleration is not, because gravity has not paused. Students who believe acceleration accompanies motion get this wrong every time, which is precisely why it is asked. It is also a good self test: if the answer feels obvious in the wrong direction, the misconception is still there.
Projectiles are two independent problems sharing a clock
Horizontal and vertical motion do not affect each other; they share only elapsed time. Solving them as one combined problem is what makes projectile questions feel hard. Splitting the page in two columns and writing time once in the middle turns most of them into arithmetic. This convention alone recovers a lot of marks.

What is AP Physics 1 Unit 1?
Kinematics: describing motion using position, velocity and acceleration, without yet asking what caused it.
Why do sign conventions cost so many marks?
Because nothing in the problem sets them. You choose, and every quantity must then obey your choice. Most wrong answers changed convention silently partway through.
Is acceleration the same as speeding up?
No. It is the rate at which velocity changes, so an object slowing down is accelerating, with a sign opposite to its motion.
How do the three graphs relate?
Slope takes you from position to velocity to acceleration. Area takes you back the other way. Questions that hand you one and ask for another are common.
What happens at the top of a vertical throw?
Velocity is zero and acceleration is not, because gravity has not paused. It is the classic test of whether the misconception is gone.
Why do projectile problems feel so hard?
Because they are solved as one problem. Horizontal and vertical motion are independent and share only time, so split the page in two and write time once.
