CHAPTER 1: BASIC CONCEPTS :green_cross:
NEWTON'S FIRST LAW :!!:
A states that an object will remain at rest or in motion in a straigth line unless acted upon by an external force
An object in motion continues in motion with the same speed and in the same direction unless acted upon by unbalanced force.
DEFINITION :warning:
MECHANICS :no_entry:
A branch of the physical sciences that is concerned with the state pf rest or motion of bodies subjected to the action of forces.
Branch of mechanics
Mechanics of Deformable Bodies
Mechanics of Fluids
Mechanics of Rigid Bodies
:green_cross:
Static
Primarily concerned to system of forces applied to body at rest.
Dynamic
Concerned with moving bodies.
FUNDAMENTAL OF E. MECHANICS :checkered_flag:
MASS
:star:
Anmeasure of the amount of material in a body. (kg)
FORCE
:star:
Represents the action of one body on another.
Point of 3 applications
Magnitude
directions
vector
TIME
:star:
A concept for measuring the succession and the duration of events or a concept for ordering the flow of events.
PARTICLE
:star:
An entity that has a mass but the size can be neglected.
SPACE
:star:
A geometric region in which even involving bodies occur.
Standard unit of length measurement is the meter(m).
RIGID-BODY
:star:
A combination of large number of particles occupying fixed positions with respect to each other.
NEWTON'S THIRD LAW :!!:
States that for every action there is an equal and opposite reaction.
A force is a push or a pull that acts upon an object as results of its interaction with another object.
Two force:
Reaction
Action
NEWTON'S SECOND LAW :!!:
States if a resultant force acts on a body, ir will cause the body to acceleration in the direction of the resultant force.
The acceleration of the body will be directly proportional to the resultant force and inverse proportional to the masss of body.
