Gravitationa Study guides, Class notes & Summaries

The gravitational force between two objects has a magnitude of F. If both masses were doubled and the distance between them doubled, the new force would have which of the following magnitudes? Select one: a. b. c. F d. 2F A certain galaxy is receding from observers on Earth at a speed of 0.94c. Within that galaxy, a star explodes, sending hot gases back towards the Earth. Relative to the galaxy, these gases travel at a speed of 0.67c. What is the speed of the gases relative to Earth? Se...

These notes cover Section D as per the IEB Physical Sciences SAGS. Included are comprehensive and annotated examples notes on Gravitational Fields, Electrostatics and Electric Fields. Although these notes are detailed, to perform well in physics, practicing textbook examples as well as past papers is imperative to make sure you understand the work.

This aesthetic, in-depth, neatly typed document summarises Section D of the IEB Grade 12 Physics syllabus: Gravitational and Electric fields. This document includes the full Section D syllabus, all definitions, additional class notes, own research notes and all relevant diagrams.

GIZMOS Student Exploration: Gravitational Flary: force, gravity, vector Prior Knowledge Questions (Do these BEFORE using the Gizmo.) On the night of a Full Moon, Mary decides to do an experiment with gravity. At midnight, she climbs into her backyard tree house, leans out the window, and holds an acorn as high as she can. She lets go and is disappointed to see the acorn plummet back down to Earth. 1. Why did the acorn fall to Earth instead of rising up to the Moon? ______________________ _...
