Module 5 Flashcards
It is Newton’s First Law which states that an object will remain in its current state unless there is a change in its equilibrium caused by an unbalanced, outside force.
Law of Inertia
It is simply balance.
Equilibrium
The state of an object’s equilibrium is known as its _ (Latin of inactive). It is best defined as the resistance of an object to change its state of motion.
inertia
If forces are _, the object will remain in its current state.
balance
If forces are _, the object will change its state.
unbalance
Isaac Newton has built the first law upon Galileo’s assumptions. In it, Galileo stated that objects eventually stop due to the force called ____, which is defined as the resistance that one surface, or object, encounters when moving another.
friction
It is defined as an influence that tends to change an object’s state of motion when left unopposed. It can also be defined as the strength or energy which is the result of physical action or movement.
Force
These are forces that two (2) objects exert whenever they are in a perceived, physical contact. Examples of these forces include friction, tension force (force resulting from pulling), normal force (force perpendicular to the surface an object is placed upon), air resistance (force exerted by air), spring force (force resulting from compression), and applied force (force directly applied to objects).
Contact forces
These are forces that two objects exert at a distance. Examples are gravitational and electromagnetic forces, wherein the second force can be divided into electrical and magnetic forces.
Noncontact Forces
These are simple diagrams that represents all forces acting on an object.
free-body diagrams
Force is a derived ___ ___
vector quantity
In Newton’s Second Law, which represents the aftermath of an object exposed to unbalanced forces, states that an object is said to be moving when it is accelerating.
Law of Acceleration
An object is said to be ___ if an unbalanced net force is applied to it, in which the acceleration of the object is directly proportional to the net force, is moving along the direction the net force is directed at, and is inversely proportional to the object’s mass.
accelerating
It is the force exerted by gravity on the object, represented by the formula, 𝐹𝑊 = 𝑚𝑔, with 𝑔 is the acceleration due to gravity
Weight (𝑭𝑾)
It is the force acting against weight, which is always perpendicular to the surface the object is resting upon.
Normal Force (𝑭𝑵)
