Pushes and Pulls: with Annie & Moby

Giới thiệu

Learning about forces and motion will help you understand the world around you and how things work. In this movie, you’ll explore forces, or pushes and pulls, and how they can change the way something moves. You’ll also learn about position, and how motion is a change of position. What are some things you push or pull to move? Speed tells us how fast something moves. Fast objects can go farther distances in a small amount of time. Did you know that you need more force to move heavier objects? Friction is a force that acts in the opposite direction of motion to slow down moving things.
