I recommend you the "Intro to Physics: Landmarks in Physics" course made by Udacity (http://www.udacity.com/overview/Course/ph100/CourseRev/1 http://www.udacity.com/overview/Course/ph100/CourseRev/1). I'm currently halfway through it and I'm having a lot of fun doing it! Here's the syllabus of the course: Unit 1: How can we measure the circumference of the Earth? Basics of geometry and trigonometry Unit 2: How do objects move? Data analysis and kinematics Unit 3: What causes motion? Forces, acceleration, and Newton’s Laws Unit 4: How can we use motion? Work, energy, and simple machines Unit 5: How can we determine our longitude at sea? Simple harmonic motion Unit 6: What is electricity? Charge and electric fields Unit 7: What is left to discover? Modern physics and open questions
