Exploring Energy: Potential vs. Kinetic Concepts
Dive into the concepts of potential and kinetic energy through labs, lectures, and discussions. Get ready for quizzes and tests on potential and kinetic energy, with opportunities for retakes. Understand the equations, types, and measurements associated with energy in motion. Explore real-world examples like a ball hitting a home run or a rocket accelerating through space. Learn about gravitational and elastic forces, and how they contribute to energy storage. Discover the relationship between mass, speed, and kinetic energy, and differentiate between the two types of potential energy.

*is done when forces applied to an object causes displacement or motion cause object to move *measured in Joules (J) = 1 Newton 1 meter or kg m m = kg m2 s2 *Work causes a change in the objects energy s2
A teacher applies a force to a wall and becomes exhausted. 1. A book falls off a table and free falls to the ground. 2. A rocket accelerates through space. 3.
*Kinetic Energy = energy due to motion *Potential Energy = stored energy that has the possibility to have motion Gravitational: downward force of gravity Elastic: produced by squeezing, compressing or stretching *Both Kinetic & Potential Energy are measured in Joules
*Kinetic Energy *Based on Mass & Speed *Kinetic Energy = 0.5 x Mass x Speed2 2 Joules Joules
1. What is kinetic energy? 2. What are the two types of Potential energy?
Determine the kinetic energy of a 625-kg roller coaster car that is moving with a speed of 18.3 m/s. KE = .05 x mass x speed2 625 Kg 36.6 m2 s2 18.3 m 2 s 625 kg KE = 0.5 = 11,437.5Joules 36.6 m2 s2
*Potential Energy *Based on object s height OR on object s stretching *Gravitational PE = mass x gravity x height Joules Joules
A 2.5 Kg dictionary is on the top shelf of a 10meter bookshelf. What is the potential energy of the dictionary? PE = mass x gravity 9.8 m/s2 x height 10 m Joules Joules 2.5 Kg PE = 2.5 Kg 9.8m s2 10 m = 245 Joules
