We help solve your homework problems, draw the answers and show you step by step how to get the answers. For Trig based Physics classes.

Do you need help doing your homework problems? Are you having trouble just getting started? Are you tired of trying to follow along with the 'how to' videos online? Why can't you just put the problem into the app and get the answer? We can.

Included in this version:
- Quick Start Guide
- Vector Calculator
- Vector Resultant Calculator
- 1-D Kinematics Calculator
- 2-D Kinematics Calculator
- Newton’s Laws Calculator
- Momentum Calculator
- Impulse Calculator
- In-Elastic Collision Calculator
- Elastic Collision Calculator
- Torque Calculator
- Net Torque Calculator

With Applications on
- Free Body Diagrams
- Object on a Flat Plane
- Object on an Incline Plane
- Object against Vertical Wall
- Tension on Object from 1 Cable
- Tension on Object from 2 Cables
- Momentum
- Impulse
- In Elastic Collisions - Conservation of Momentum
- Elastic Collisions - Conservation of Kinetic Energy and Momentum
- Object in Free Fall
- Projectile Shot straight up
- Projectile in Motion at an angle
- Torque
- Net Torque (Beam)
- Net Torque (Compound Wheel)

And we show you how we did it.

Additionally, if your teacher throws you a curve ball, we also provide you the ability to model a fixed scenario of your choosing in the iPad version. While iterating the scenario you can change specific variables-including incline angle, force applied, force applied angle, mass, and coefficient of static friction. Modeling functions generate step by step reports for each answer so you can check your work.

Free Trial is not by time but rather by usage. Specifically, each time you model a scenario, or run a simulation, or solve a Kinematic equation you will use one of 3 free attempts.  

After you have completed the free trial you can can access the app with one of the subscription options below. Some modules use more than one use to solve the final problem including Impulse and Collisions.

Users can solve more homework problems when they watch Reward Ads to earn more uses. Or they can pay for an Ad Free Pass.

Physics homework

Great job on the free body diagram. I used this to do my summer physics homework. It’s not written exactly the way my professor writes it but still works. I really like how you can change the mass and angles.

Developer Response ,

Thank you for your feedback. We are always open to suggestions and want to make the ‘Show Work’ feature as helpful as possible.

Very Helpful

I used the Kinematics and Projectiles the most bc i joined half way thru summer class. i would give 5 but it could flow a little smoother.
