LESSON 1 Flashcards
The science which describes and predicts the condition of rest or motion of bodies under the action of forces
Mechanics
It is under mechanics of rigid bodies which deals with bodies at rest
Statics
It is under mechanics of rigid bodies which deals with bodies at motion
Dynamics
The geometric region occupied by bodies whose positions are described by linear and angular measurements relative to a coordinate system.
Space
The measure of succession of events
Time
It is the measure of the inertia of a body, which is its resistance to a change of velocity.
Mass
It is the action of 1 body to another
Force
The action of force is characterized by its magnitude, direction, and _______
point of application
A body with negligible dimensions
Particle
A body is ____ if the change in distance between any two of its points is negligible for the purpose at hand
rigid
It states that if the resultant force = 0, it will remain at rest or will move with constant speed in a straight line
First Law
It states that if the resultant force on a particle is not zero, it will have acceleration proportional to magnitude of resultant and direction of its resultant force
Second Law
Second Law Formula
F=ma
It states that forces of action and reaction between bodies in contact have same magnitude, same line of action, and opposite sense
Third Law
It states that 2 particles of mass M and m are mutually attracted with equal and opposite forces F and -F of magnitude F
Newton’s Law of Gravitaion
