In this video David explains the concepts in Work and Energy and does an example problem for each concept. Link for document: https://www.dropbox.com/s/t1w6xlnkozzel17/Energy%20review.pdf?dl=0. Created by David SantoPietro.

Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink.

By Kenneth Tan and Louis Tay, Purdue University. The relationships we cultivate in our lives are essential to our well-being—namely, happiness and health. Why is that so? We begin to answer this question by exploring the types of relationships—family, friends, colleagues, and lovers—we have in our lives and how they are measured. We also explore the different aspects of happiness and health, and show how the quantity and quality of relationships can affect our happiness and health.

Explores the changing map of the public and the private in pre-industrial and modern societies and examines how that map affected men's and women's production and consumption of goods and leisure. The reproductive strategies of women, either in conjunction with or in opposition to their families, is another major theme. How did an ideal of the "domestic" arise in the early modern west, and to what extent did it limit the economic position of women? How has it been challenged, and with what success, in the post-industrial period? Focuses on western Europe since the Middle Ages and on the United States, but some attention to how these issues have played themselves out in non-Western cultures. This course will explore the relation of women and men in both pre-industrial and modern societies to the changing map of public and private (household) work spaces, examining how that map affected their opportunities for both productive activity and the consumption of goods and leisure. The reproductive strategies of women, either in conjunction with or in opposition to their families, will be the third major theme of the course. We will consider how a place and an ideal of the "domestic" arose in the early modern west, to what extent it was effective in limiting the economic position of women, and how it has been challenged, and with what success, in the post-industrial period. Finally, we will consider some of the policy implications for contemporary societies as they respond to changes in the composition of the paid work force, as well as to radical changes in their national demographic profiles. Although most of the material for the course will focus on western Europe since the Middle Ages and on the United States, we will also consider how these issues have played themselves out in non-western cultures.

Learn about conservation of energy with a skater dude! Build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. You can also take the skater to different planets or even space!

Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!

Explores how public policy and private markets affect housing, economic development, and the local economy; provides an overview of techniques and specified programs policies and strategies that are (and have been) directed at neighborhood development; gives students an opportunity to reflect on their personal sense of the housing and community development process; emphasizes the institutional context within which public and private actions are undertaken.

This subject investigates the special relation of women to several musical folk traditions in the British Isles and North America. Throughout, we will be examining the implications of gender in the creation, transmission, and performance of music. Because virtually all societies operate to some extent on a gendered division of labor (and of expressive roles) the music of these societies is marked by the gendering of musical repertoires, traditions of instrumentation, performance settings, and styles. This seminar will examine the gendered dimensions of the music -- the song texts, the performance styles, processes of dissemination (collection, literary representation) and issues of historiography -- with respect to selected traditions within the folk musics of North America and the British Isles, with the aim of analyzing the special contributions of women to these traditions. In addition to telling stories about women's musical lives, and studying elements of female identity and subjectivity in song texts and music, we will investigate the ways in which women's work and women's cultural roles have affected the folk traditions of these several countries.

A realistic mass and spring laboratory. Hang masses from springs and adjust the spring stiffness and damping. You can even slow time. Transport the lab to different planets. A chart shows the kinetic, potential, and thermal energy for each spring.

In this class we will come to understand the vast changes in Spanish life that have taken place since Franco's death in 1975. We will focus on the new freedom from censorship, the re-emergence of movements for regional autonomy, the new cinema, reforms in education and changes in daily life: Sex roles, work, and family that have occurred in the last decade. In so doing, we will examine myths that are often considered commonplaces when describing Spain and its people.
