Case Study: Solving a Multi-Part Physics Problem

I tested the tool with a standard mechanics problem to see how it performed.

I entered the following question:

'A student is pushing a 12 kg box across a horizontal floor at constant speed. The coefficient of kinetic friction between the box and the floor is 0.25.

(a) Draw a free-body diagram showing all the forces acting on the box.
(b) Calculate the magnitude of the frictional force acting on the box.
(c) What is the magnitude of the applied force the student must exert to keep the box moving at a constant speed?
(d) If the student instead pushes the box with a force of 50 N, what will be the acceleration of the box?'

The AI correctly identified all the forces for the free-body diagram and accurately calculated the frictional force. It also correctly determined the applied force needed for constant speed and the acceleration with the new force. The step-by-step solution was easy to follow and clearly explained the formulas used.

How to Use It

1. Visit physicsai.io and create an account. New users receive up to 50 free AI answers per day.

2. Type your physics question directly into the input field, or upload a photo of handwritten or printed problems. The AI handles both text and image inputs.

3. The AI identifies core concepts, selects appropriate formulas, and performs calculations with scientific precision. Solutions include concept explanations, mathematical steps, and final answers.

Pros

• Free Daily Access: The free plan offers up to 50 solutions a day, which is great for most students.
• Supports Multiple Subjects: It can also help with math, chemistry, and more.

Cons

• Subscription for Heavy Use: If you need more than 50 answers a day, you’ll have to pay for a subscription.
• Potential for Over-Reliance: As with any tool that provides answers, there’s a risk of becoming too dependent on it and not learning the material deeply.
