TYPES OF POTENTIAL AND KINETIC ENERGY CHEMICAL POTENTIAL

TYPES OF POTENTIAL AND KINETIC ENERGY

CHEMICAL POTENTIAL ENERGY • a form of potential energy • usually stored in a medium and released later into different forms. Examples include: • food we eat (stored in the body) • batteries used in our electrical devices • petroleum used to power cars to move Can you think of any other examples in your daily life?

ELASTIC POTENTIAL ENERGY • a form of potential energy • energy stored in elastic materials as a result of stretching and compressing Examples include: • Jack-in-the-box • rubber band • stretching a catapult Do you think an object has more or less energy when stretched? What about when that object is compressed?

ELECTRICAL ENERGY • a form of kinetic energy • energy that arises due to the movement of charged particles in an object Why are some materials, such as plastic and wood, unable to conduct electricity? What is an example of electrical energy that originates in nature?

MECHANICAL ENERGY (energy of motion) • a form of kinetic energy • energy of a moving object • the faster an object moves, the more energy it possesses What is an example of motion energy in nature? Using the idea of mechanical energy, why do car crashes always result in devastating consequences?

ELECTROMAGNETIC ENERGY • a form of kinetic energy • energy that travels by waves/particles From this diagram, what are other examples of electromagnetic energy that you are familiar with? Where does sunlight fall under in the spectrum?

THERMAL ENERGY (heat) • a form of kinetic energy • energy due to the motion of atoms within substances Do atoms more quicker or slower at a higher temperature?

SOUND ENERGY • a form of kinetic energy • energy due to the vibration of air particles, causing the air around the object to produce a sound which eventually reaches our ears Can sound be heard in space?

C A B D GRAVITATIONAL POTENTIAL ENERGY • a form of potential energy • energy stored in an object as a result of its position from the ground due to the attractive force by Earth • the heavier and higher the object is, the more energy it possesses At which point of the rollercoaster track would the gravitational potential energy of the cart be the least?
