This educational content explores the different forms of energy, essential for 4th-grade vocabulary development. It covers potential energy—energy stored due to an object's position—illustrated by a roller coaster's height. Kinetic energy is explained as the energy of motion, peaking at the bottom of a hill. The section on sound energy describes how it travels through matter in waves, with concepts such as vibration, pitch, and volume. Lastly, light energy is introduced, emphasizing its ability to move through space and matter, alongside mechanical energy's role in initiating motion.
E N D
4th Grade Vocabulary Part Five Forms of Energy
Energy The ability to cause changes in matter
Potential Energy The energy an object has because of its place or its condition A roller coaster has the most potential energy at the top of a hill.
Kinetic Energy The energy of motion A roller coaster has the most kinetic energy when it is at the bottom of a hill.
Sound Energy A form of energy that travels through matter as waves
Sound Wave A moving pattern of high and low pressure that you can hear
Vibration Rapid back and forth movement of matter that produces sound (examples: violin string, vocal cords)
Pitch The speed with which sound particles vibrate; the faster the waves the higher the pitch
Volume The loudness of sound
Light Energy • Energy that can travel through empty space and some kinds of matter
Mechanical Energy Energy that puts something in motion
