We visit a bustling port on Georgia's coast to illustrate how free body diagrams help us analyze forces. Useful rules for drawing free body diagrams are also explained.
Newton's second law is explained as we examine the forces of gravity, tension, friction, spring, and the normal. We use an example problem to analyze the forces acting on an object resting on a surface.
We continue to investigate Newton's second law and explore the force of friction in greater detail. We also look at the forces acting on an object in both the horizontal and vertical directions.
We travel to an indoor skydiving facility to investigate the force of gravity. Concepts such as weight, Newton's Law of Gravitation, air resistance, and terminal velocity are discussed.
We travel to an amusement park to explore circular motion. We work through an example problem and define such terms as tangential velocity and centripetal acceleration.
In this segment we define the terms momentum and impulse. We see the impulse-momentum theorem in action by analyzing the motion of a freerunner and the motion of an egg hitting two very different surfaces.
In this segment, we differentiate between elastic and inelastic collisions. The conservation of momentum and the conservation of energy are explored as we do examples involving these two types of collisions.
Work and energy are explored in this segment as we look at the work done by various types of forces. We also investigate what it means for the work done by an object when displacement and force are oriented in a variety of different ways.
We explain the work-energy theorem and solve an example problem involving the equations for work and kinetic energy. We also discuss when work has a positive or negative value.
