Lecture 2 Play Video Introduction to Physics In this video lecture, Prof. Jerzy Wrobel talks about structure of physics. Lecture 3 Play Video Scalar Quantities In this video lecture, Professor Jerzy Wrobel discussed properties of scalar quantities and introduces concepts of time, distance, mass and length. Lecture 4 Play Video Area, Volume & Density In this video lecture, Prof. Jerzy Wrobel explains definitions of area, volume and density and solves example problems related to these concepts. Lecture 5 Play Video Vectors In this video lecture, Professor Jerzy Wrobel discusses the properties of vectors. Lecture 6 Play Video Scalar Product and Cartesian Coordinate System In this video lecture, Prof. Jerzy Wrobel explains introduces scalar product and shows how to identify components of vectors. Lecture 7 Play Video Vector Quantities In this video lecture, using as example of position, Professor Jerzy Wrobel shows how to relate a vector physical quantity to a vector (arrow) and an array of scalar components. Lecture 8 Play Video Velocity and Acceleration In this video lecture, Prof. Jerzy Wrobel explains the concept of derivative of a scalar and vector function of one variable. In terms of these concepts, he defines velocity and acceleration. Lecture 9 Play Video Motion with Constant Velocity In this video lecture, Prof. Jerzy Wrobel analyzes position, velocity and acceleration in the motion with constant velocity. Lecture 10 Play Video Motion with Constant Acceleration In this video lecture, Prof. Jerzy Wrobel analyzes position, velocity and acceleration in the motion with constant acceleration. Lecture 11 Play Video Inverse Relations In this video lecture, Prof. Jerzy Wrobel analyzes shows how to find velocity from acceleration and position from velocity. Lecture 12 Play Video Galilean Transformation In this video lecture, Prof. Jerzy Wrobel discusses relations between descriptions of motion in two reference frames. He also explains the differences between speed and velocity and talks about average values of physical quantities. Lecture 13 Play Video Laws of Motion In this video lecture, Prof. Jerzy Wrobel explained Newtons laws of motion and discussed the concept of force. He has also shown how to construct a free body diagram. Lecture 14 Play Video Laws of Motion In this video lecture, Prof. Jerzy Wrobel reviewed the four fundamental interactions and introduces the concept of a force field. Lecture 15 Play Video Laws of Motion In this video lecture, Prof. Jerzy Wrobel talks about weight, normal force, and static friction. Lecture 16 Play Video Laws of Motion In this video lecture, Prof. Jerzy Wrobel talks about kinetic friction, tension, drag, lift. Lecture 17 Play Video Uniform Circular Motion In this video lecture, Prof. Jerzy Wrobel introduced the vector product of vectors and used it in a description of uniform circular motion. Lecture 18 Play Video Inertial Forces In this video lecture, Prof. Jerzy Wrobel explained how the non-inertiality of a reference frame results in the inertial forces. Lecture 19 Play Video Inertial Forces In this video lecture, Prof. Jerzy Wrobel explained how the non-inertiality of a reference frame results in the inertial forces. Lecture 20 Play Video Newton's Second Law in a Non-Inertial Reference Frame In this video lecture, Professor Jerzy Wrobel compares solutions to a problem in an inertial and non-inertial reference frames. Lecture 21 Play Video The Work-Energy Theorem (Part I) In this video lecture, Prof. Jerzy Wrobel defined the concepts of work and kinetic energy and has explained the relation between them. Lecture 22 Play Video Lecture 22 Lecture 23 Play Video Mechanical Energy In this video lecture, Prof. Jerzy Wrobel introduces the concept of mechanical energy and relates it to non-conservative work. Lecture 24 Play Video Applications of the Work-Energy Theorem In this video lecture, Prof. Jerzy Wrobel shows how to use the work-energy theorem to relate interaction with motion. Lecture 25 Play Video Relation between Descriptions of Interaction and Descriptions of Motion In this video lecture, Professor Jerzy Wrobel talks about applicability of Newtons second law of motion versus the work energy theorem. He also shows the relationship between potential energy and conservative force. Lecture 26 Play Video Impulse-Momentum Theorem In this vidoe lecture, Prof. Jerzy Wrobel defines momentum of a particle and impulse, and relates these two quantities through the impulse-momentum theorem.
