Elastic Collision and Center of Mass Velocity

Fluid mechanics is the branch of physics concerned with the mechanics of fluids in ______.

Fluid mechanics deals with problems such as surface tension, fluid statics, flow in enclosed bodies, flow around bodies, flow stability, etc. The applications are enormous, including breathing, blood flow, swimming, pumps, fans, turbines, airplanes, ships, rivers, windmills, pipes, missiles, icebergs, engines, filters, jets, and ______.

In physics, a fluid is a substance that continually deforms (flows) under an applied ______ stress.

Fluids are a phase of matter and include ______ and gases.

At the end of the unit on fluid mechanics, you will be able to distinguish between elastic and ______ materials properties.

The center of mass of four objects situated along the y-axis can be determined by their masses and ______ from the origin.

______ is the study of the physics of motions and how it relates to the physical factors that affect them, like force, mass, momentum, and energy.

Mechanics may be divided into two branches: Dynamics, which deals with the motion of objects with its cause – ______.

Kinematics describes the possible motions of a body or system of bodies without considering the ______.

The simplest mechanical system is the ______, defined as a body so small that its shape and internal structure are of no consequence in the given problem.

More complicated is the motion of a system of two or more particles that exert forces on one another and possibly undergo forces exerted by bodies outside of the ______.

The principles of mechanics have been applied to three general realms of phenomena: celestial bodies, ordinary objects on Earth, and ______.

The engineer who designs bridges or aircraft may use the Newtonian laws of mechanics with confidence, even though the forces may be very complicated, and the calculations lack the beautiful simplicity of celestial mechanics. The third realm of phenomena comprises the behavior of matter and electromagnetic radiation on the atomic and subatomic scale. Learning Objectives: After going through this unit students will be able to:  Understand the general feature of motion of a particle. Know how particles interact with the action of force. Explain the relationship between force and work done. 15 2.1.Kinematics in One and Two Dimensions Self Diagnostic Test  What does kinematics deals about? Can you state the kinematical quantities that describe the motion of objects? Can you distinguish instantaneous and average velocities?And accelerations?A formal study of physics begins with kinematics. The word ―kinematics‖ comes from a Greek word ―kinesis‖ meaning motion, and is related to other English words such as ―cinema‖ (movies) and ―kinesiology‖ (the study of human motion). Kinematics is the branch of mechanics that describes the motion of objects without reference to the causes of motion (i.e., forces). Kinematics is concerned on analyzing kinematical quantities used to describe motion such as velocity, acceleration, displacement, time, and trajectory. Objects are in motion all around us.
