Projectile motion, mechanics and electricity and magnetism. Solid understanding of algebra and a basic understanding of trigonometry necessary.
In this tutorial we begin to explore ideas of velocity and acceleration. We do exciting things like throw things off of cliffs (far safer on paper than in real life) and see how high a ball will fly in the air.
You understand velocity and acceleration well in one-dimension. 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.
Forces and Newton's Laws of Motion
This tutorial 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.
Work and energy
Work and energy. Potential energy. Kinetic energy. Mechanical advantage. Springs and Hooke's law.
Impacts and linear momentum
Linear momentum. Conservation of momentum. Elastic collisions.
Moments, torque and angular momentum
Thinking about making things rotate. Center of mass, torque, moments and angular velocity.
Classical gravity. How masses attract each other (according to Newton).
Pendulums. Slinkies. You when you have to use the bathroom but it is occupied. These all go back and forth over and over and over again. This tutorial explores this type of motion.
