Chapter 1: Electrostatics
19.1 Coulomb’s law
19.2 Electric field
19.3 Charge in a uniform electric field
19.4 Electric Potential
6161103 3.4 three dimensional force systems
1) Three-dimensional force systems involve resolving forces into x, y, and z components and using the equations of equilibrium to solve for unknown forces.
2) Examples are provided of using free body diagrams and the equations of equilibrium to solve for tensions in cables, magnitudes of applied forces, and stretches of springs in static systems with multiple forces.
3) Unknown forces and stretches are determined by setting the vector sum of the forces in x, y, and z directions equal to zero and solving the resulting simultaneous equations.
Newton’s Laws of Motion with Real Life Examples
Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. It is also known as the law of inertia. Examples given are a hockey puck slowing down due to friction on the ice and a kicked ball in space continuing forever without air resistance or gravity. Newton's second law explains that acceleration is produced by an unbalanced force acting on an object, with greater force needed to accelerate objects with greater mass. Pushing a truck requires more force than pushing a car. Newton's third law states that for every action there is an equal and opposite reaction, such as a boat moving backward when a person jumps
Sem5 physics
This document outlines a course on thermal and statistical physics. It will introduce concepts of statistical mechanics and quantum statistics over 15 weeks. Students will learn fundamental concepts, distribution laws, connections between entropy and quantum states, and properties of systems using statistical methods and thermodynamic potentials. Assessment includes quizzes, assignments, tests and a final exam. The goal is for students to understand thermal and statistical physics and solve related problems.
