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. The series is comprised of seven units of study divided into segments. The concepts in this unit are: • force and its measurement • balanced and unbalanced forces • the difference between mass and weight • forces in relation to changes in motion
Physics in Motion Unit 4: Momentum & Energy Work and energy are explored in this segment as we look at the work done by various types of forces. Georgia Public Radio® GPTV® 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.Obtain, evaluate, and communicate information about the importance of conservation laws for mechanical energy and linear momentum in predicting the behavior of physical systems.Ask questions to compare and contrast open and closed systems.Obtain, evaluate, and communicate information to explain the relationships among force, mass, and motion.-Define work, explaining that it is a scalar quantity that depends on the force applied to an object combined with the object’s displacement.-Show that work is positive when the force and the object’s displacement are in the same direction, negative when force and displacement are in opposite directions, and zero if force and displacement are perpendicular or if the object doesn’t move at all or if the force exerted on the object is zero.-Define energy. Sign up to receive GPB Event announcements via Email.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 define the terms momentum and impulse. Physical Health and Wellness Segment B: Conservation of Momentum The law of conservation of momentum is explained qualitatively and mathematically through examples involving billiards and roller skaters.

Powered by Create your own unique website with customizable templates. Note that all work requires energy.-Review the difference between open and closed systems and apply this knowledge to how an object gains and loses energy. Under each segment, you will find support materials designed to provide practice and reinforce concepts. work (W) - when a force causes displacement of an object.

-Explain that momentum is a vector quantity and the direction matters.-Explain how an object’s change in momentum depends on the net force it experiences and the length of time the force is applied.-Define impulse and how it relates to momentum through the impulse-momentum theorem.-Discuss the real-life implications of manipulating variables within the impulse-momentum theorem.
