What are the scientific principles that explain gravity and electromagnetism?
GRAVITY
1. How would one distinguish between mass and weight? 0807.12.4
2. How do mass and distance influence the gravitational force between objects? 0807.12.5
3. How is the motion of objects in the solar system affected by gravity? 0807.12.6
Key vocabulary: mass, gravitational force, weight, Newton, spring scale, triple beam balance, calibrate, inertia, Law of Universal Gravitation
MAGNETISM
1. What are the properties of magnets? 0807.12.1, 0807.12.2
2. How can electricity be used to create a magnetic field? 0807.12.2
3. How can a magnet be used to create an electric current? 0807.12.1
4. How can you distinguish between the Earth's magnetic field and the magnetic fields that surround a magnet and an electromagnet? 0807.12.3
Key vocabulary: domains, poles, magnetism, magnetic field lines, electromagnetism, solenoid, galvanometer, ammeter, amperes (amps), Oersted, Faraday, electric generator, electric motor
