Unit 8 Part 1

For unit 8 today, we learned about different types of energy which are potential energy of gravity, potential energy of spring, kinetic energy, and work. Potential energy is the energy that a stationary object has relative to its height, mass, etc. and uses the formula "mgh." Potential energy of spring has the equation of "1/2 spring constant * d^2." Kinetic energy is energy of motion and uses the formula "1/2 m * v^2." All energy is conserved, therefore if an object at rest at a certain height has "x" joules of potential energy, when the object is about to hit the ground after falling from that height will have "x" joules of kinetic energy. The two pictures below represent the object at rest with "x" joules of potential energy and the same amount of kinetic energy as it reaches 0 meters.
