Gravitational and Electric Forces

This study guide covers gravitational force, starting with a basic introduction and its importance. It details the force of gravity near Earth's surface (using F_g = mg) and Newton's Law of Universal Gravitation (using F_g = G(m₁m₂)/r²). It explains the direct and inverse square relationships within the law and connects gravity to circular motion and energy. Finally, it provides key exam tips, focusing on applying the equations, common pitfalls, and practice questions.
