Physics problems with answers
Physics problems on STEMinute are short, concrete and solvable with a few lines of math. You work with forces and motion, energy and work, waves and sound, light, heat and simple circuits. Each problem gives you numbers and asks for one result, such as a speed, a force or a distance. The best way to improve is to draw the situation first, write down what you know, pick the formula that connects it to what you want, and check that your units agree.
