Chapter 9. Impulse and Momentum - Physics & Astronomy

Chapter 9. Impulse and Momentum Explosions and collisions obey some surprisingly simple laws that make problem solving easier when comparing the situation before and after an interaction. Chapter Goal: To introduce the ideas of impulse and momentum and to learn a new problem-solving strategy based on conservation laws.

Chapter 22 Magnetism - Physics & Astronomy

Magnetism – Is this a new force? Bar magnets (compass needle) align themselves in a north-south direction. Poles: Unlike poles attract, like poles repel Magnet has NO effect on an electroscope and is not influenced by gravity Magnets attract only some objects (iron, nickel etc) No magnets ever repel non magnets
