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.

Study Notes
Projectile Motion
- The velocity of a ball can be calculated after a head-on elastic collision.
- The velocity of the center of mass can be found before and after a collision.
Fluid Mechanics
- Fluid mechanics is the study of the mechanics of fluids in motion (fluid dynamics) or at rest (fluid statics) and the forces on them.
- Fluids include liquids and gases, and are a phase of matter.
- Applications of fluid mechanics include breathing, blood flow, swimming, pumps, fans, turbines, airplanes, ships, rivers, windmills, pipes, missiles, icebergs, engines, filters, jets, and sprinklers.
Vectors
- Vectors can be added and subtracted to find resultant vectors.
- Unit vectors can be found in the direction of the resultant of vectors.
Kinematics and Dynamics of Particles
- Mechanics is the study of the physics of motions and how it relates to physical factors that affect them, like force, mass, momentum, and energy.
- Mechanics can be divided into two branches: Dynamics, which deals with the motion of objects with its cause – force; and kinematics, which describes the possible motions of a body or system of bodies without considering the cause.
- The principles of mechanics have been applied to three general realms of phenomena: celestial bodies, ordinary objects on Earth, and the behavior of matter and electromagnetic radiation on the atomic and subatomic scale.
Kinematics in One and Two Dimensions
- Kinematics is the branch of mechanics that describes the motion of objects without reference to the causes of motion (i.e., forces).

Description
This quiz covers concepts related to an elastic collision between two balls of different masses and velocities, and the calculation of their velocities after the collision as well as the center of mass velocity. It also includes problems involving the position of objects along the y-axis and determining the center of mass in that system.
