IGCSE Physics Edexcel: Astrophysics with complete solution

What is a universe? - ANSWER-A large collection of billions of galaxies What is a galaxy? - ANSWER-A large collection of billions of stars What galaxy is the Solar System in? - ANSWER-Milky Way Galaxy Why does gravitational field strength vary? - ANSWER-The gravitational field strength of a body is dependent on the mass. A massive object like a star will have a large g-field. The Moon has less mass than Earth, so its gravitational field strength is weaker. A planet with a larger radius wil...

1. MOTION, FORCES AND ENERGY 1.2. Motion Speed is defined as the distance travelled per unit time. Use the equation v = d Where: 1.1. Physical quantities and measurement techniques v is speed d is distance t is time Velocity is defined as the speed in a given direction. Liquids: A graduated measuring cylinder. A pipette (accurate for one specific measurement) Time: Stopwatch (reading to 0.1s or better) Length: Metre rule (graduated in mm) Micrometer Screw Gauge Vern...
