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

The Simple Pendulum A pendulum is made by suspending a mass m at the end of a string of length L Find the frequency of oscillation for small displacements mg

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

At ordinary temperature, matter exists in one of three states Solid- has a shape and forms a surface Liquid- has no shape but forms a surface Gas-has no shape and forms no surface What do we mean by“ fluids”? F| uids are“ substances that flow

The kinetic energy of a rotating system looks similar to that of a

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

The impulse of the force action on an object equals the change in momentum of the object

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

Work Kinetic-Energy Theorem: (Net Work done on object] change in kinetic energy of object
