Energy and Speed

Published on August 28, 2022 by

In this video, students will learn about the relationship between speed and energy. Energy of motion is known as kinetic energy and speed is a measure of how fast an object travels in a particular amount of time. An object’s speed is determined by several factors. By changing these factors, we can not only improve its speed, but also its kinetic energy. For instance, when the speed of an object gets doubled, its kinetic energy is increased by four times.

This video also features an experiment, using marbles and a loop track, to explore the factors that can affect the speed of an object.

The video satisfies the 4-PS3-1 requirement of fourth-grade science proficiency.

Students who demonstrate understanding can: 4-PS3-1. Use evidence to construct an explanation relating the speed of an object to the energy of that object.
