1.Onedimensional motion
In this tutorial we begin to explore ideas of velocity and acceleration. We do exciting things like throw things off cliffs (far safer on paper than in real life) and see how high a ball will fly in the air.
2.Twodimensional motion
You understand velocity and acceleration well in onedimension. Now we can explore scenarios that are even more fun. With a little bit of trigonometry (you might want to review your basic trig, especially what sin and cos are), we can think about whether a baseball can clear the "green monster" at Fenway Park.
3. Forces and Newton's laws of motion
This is the meat of much of classical physics. We think about what a force is and how Newton changed the world's (and possibly your) view of how reality works.
4.Centripetal force and gravitation
Learn about centripetal acceleration and centripetal force. Also, learn about the universal law of gravitation and gravitational orbits.
5.Impacts and linear momentum
Momentum ties velocity and mass into one quantity. It might not be obvious why this is useful, but momentum has this cool property where the total amount of it never changes. This is called the conservation of momentum, and we can use it to analyze collisions and other interactions. Bam!
