Physics 1 details
Thinkwell's Physics I is a calculus-based college-level physics course, intended for physics majors as well as for engineering and other science students. It includes topics that are generally covered in the first semester of a two-semester sequence.
It's a great head start for the college-bound math, science, or engineering student.
Calculus is a prerequisite.
Thinkwell's Physics 1 has all the features your home school needs:
- More than 140 educational video lessons
- 104 available contact hours (What is this?)
The number of contact hours in a course reflects the amount of time a student will typically spend completing the assignments in each course (i.e. watching videos, doing exercises, taking exams, etc...). Many people think about contact hours as the "seat time" for a course. Thinkwell provides this information so you can ensure that the amount of instruction in a Thinkwell course meets the standards and requirements for your state or region.
- 35-week lesson plan with daily assignments (see lesson plan)
- 1000+ interactive physics exercises with immediate feedback allow you to track your progress (See sample)
- Practice tests and final tests for all 11 chapters, as well as a midterm and a final
- Printable illustrated notes for each topic
- Glossary of more than 150physics terms
- Engaging content to help students advance their knowledge of physics:
- Kinematics and motion
- Newton's three laws of physics
- Work, energy, and power
- Momentum
- Extended objects
- Gravity
- Fluid statics and dynamics
- Einstein’s theory of relativity and relativistic dynamics
