Kepler's first law

Each planet's orbit about the Sun is an ellipse. The Sun's center is always located at one focus of the orbital ellipse. The Sun is at one focus. The planet follows the ellipse in its orbit, meaning that the planet to Sun distance is constantly changing as the planet goes around its orbit.

Kepler's second law

Kepler's Second Law says says that a line running from the sun to the planet sweeps out equal areas of the ellipse in equal times. This means that the planet speeds up as it approaches the sun and slows down as it departs from it.

E: CONTENT- METALS

INTRODUCTION Metals possess a distinctive set of physical properties that distinguish them from non-metals. They are renowned for their excellent electrical and thermal conductivity, enabling efficient transfer of electricity and heat. Additionally, metals exhibit notable malleability, allowing them to be shaped into thin sheets, and ductility, enabling them to be drawn into wires. Their characteristic metallic luster arises from their ability to reflect light due to free electrons on their surface. Metals also tend to have high densities, providing strength and durability in various applications. OBJECTIVES 1. Define the term "metal" and list its key physical properties. 2. Recall examples of metals commonly used in electrical conductivity applications. 3. Identify the characteristic that gives metals their metallic luster. 4. Explain why metals are good conductors of electricity and heat. 5. Describe how malleability and ductility contribute to the versatility of metals in ...
