Tutoring AP Physics, Springs/Conservation of Energy

We started with a problem involving gravitational potential energy, kinetic energy, and elastic potential energy with a mass and a spring.

Work and energy both have units of Joules.

Made an analogy to a trampoline for the spring. Used the concept of conservation of energy. Energy changed forms a few times.

Another problem involved friction and an incline with and without friction. The version with friction was a bit more complicated and required more algebra, factoring out common terms.

For a calculus problem, getting the volume in terms of one variable using a ratio of radius/height was helpful.
