Описание к видео Grade 4 Science Revision | Energy & Motion | Solving Unit 2 Ministry Class Book Questions 2026

Welcome, Grade 4 students, to your Science revision session on New Brains Egypt! 🚀

In this comprehensive video, Ms. Maryam Mohamed walks you through the most important questions from the Ministry Class Book for Unit 2: Energy and Motion. We cover critical concepts like Potential Energy, Kinetic Energy, and Force, using real-world examples like roller coasters and cars.

📖 Key Topics Covered:

Roller Coaster Energy: Why does a roller coaster need electricity to go up but not to come down? Understanding the conversion between Potential and Kinetic energy. [00:35]

Friction Force: How friction between tires and the road slows down a car. [02:51]

Balanced vs. Unbalanced Forces: Why objects move in the direction of the greater force. [04:10]

Types of Potential Energy: Exploring Gravitational Potential Energy (objects on a height) and Chemical Potential Energy (stored in food and batteries). [06:26]

Work and Energy: Defining "Work" as the result of a force moving an object over a distance. [15:32]

Energy Transfers in Appliances: How energy changes form in flashlights, fans, and ovens. [19:47]

Factors Affecting Energy: How mass and height impact gravitational potential energy. [20:48]
