The Physics of Difficult Experiments demonstrates a typical mechanics situations common to many senior Physics courses such as Circular motion, Projectile Motion, Straight line motion, Inclined plane. Describing these motions in terms of forces and energy transfers this program covers the topic of motion using a series of large scale, real life examples. In doing so it deals with the real life issues such as uncontrolled variables of non-uniform friction and subsequent energy loss. Each topic is reinforced with detailed analysis and discussion.
