An Example Consider the following two cases

Homework 6: due after midterm week Chapter 6: Work and Energy Definition of work Work-kinetic energy theorem

Problem: How High? A projectile of mass m is launched straight up from the surface of the earth with initial speed vo. What is the maximum distance from the center of the earth Rmax it reaches before falling back down

The lever arm is the perpendicular distance from the axis of rotation to a line drawn along the direction of the force

Today' s topics Fluids in motion Bernouilli’ s equation Viscous fluids Simple oscillations

Temperature: measure of the motion of the individual atoms and molecules in a gas liquid or solid related to average kinetic energy of constituents High temperature: constituents are moving around energetically

A practical \blue-collar science initially concerned with economics industry, real life problems DYNAMICS--Concerned with the concepts of energy transfers between a system and its environment and the resulting
