Force
push or pull; required to change an object’s motion.
Contact and Field
What are the two major types of force?
Vector
show magnitude and direction
Electromagnetic, Strong Nuclear, Gravitation, and Weak Nuclear
What are the four forces known in the universe?
Electromagnetic
Caused from electric an magnetic interactions
Strong Nuclear
Responsible for holding nucleus together in the atom
Strong Nuclear
Known as the strongest force out of the four forces known in the universe
Strong Nuclear
It acts over the shortest distance out of the four forces
Gravitation
Is regarded as the weakest force out of the four forces
Gravitation
Known to act over the longest distance
Weak Nuclear
Is the force responsible for radioactivity in atoms
Contact Force
Exists when an object from the external world touches a system and exerts a force on it
Contact force
Example includes: If you push it, you are exerting a __________ force
Contact forces
“If you put it down, no longer interacting… so no more force from you” This example is known as?
Field Forces
Is a type of force defined “an object can move without something directly touching it”
Gravity, Magnetic field, Electric, Nuclear, Applied, and Spring
Give 6 examples of field forces
Friction and Tension
Give 2 examples of Contact Forces
Inertial Mass
measurement of how difficult it is to change the objects velocity
Inertia
Resistance to change in velocity
Mass is a measurement of an object’s inertia
What is inertia relative to mass?
Isaac Newton
an English scientist and mathematician famous for his discovery of the law of gravity also discovered the three laws of motion.
Newton’s Law of Motion
describe the motion of all objects on the scale we experience in our everyday lives
Newton’s First Law of Motion
An object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an unbalanced force.
Newton’s Second Law of Motion
Force equals mass times acceleration
 (F = ma).
Newton’s Third Law of Motion
For every action there is an equal  and opposite reaction.
An object in motion stays in motion, and an object at rest stays at rest, unless acted on by an unbalanced force.
Newton’s First Law of Motion
Force
It takes ______ to change the motion of an object.
Balanced
If the forces on an object are equal and opposite, they are said to be
No change
If the forces acting upon an object is said to be balanced, the object will experience _________ change in motion
Unbalanced
If the forces acting upon an object are not equal and opposite, then the forces are
the motion of the object changes
If the forces acting upon an object is said to be unbalanced, What happens then?
Law of Inertia
Newton’s First Law of Motion is also called?
Inertia
The tendency of an object to resist changes in its state of motion
All object have inertia
The First Law states that
More inertia
The more mass an object has, the ____ ______ it has
Acceleration
A measurement of how quickly an object is changing speed
Force equals mass time acceleration/ F=ma
What is the equation for newton’s second law?
Unbalanced force
causes something to accelerate
Net force
The sum total and direction of all forces acting on the object.
Net force
Always causes acceleration
directly proportional
Force is ______________ to mass and acceleration. Imagine a ball of a certain mass moving at a certain acceleration. This ball has a certain force.Â
Small force = Small acceleration, Large Force = Large acceleration
In Layman's terms, what is newton’s second law of motion all about?
Inversely related
Acceleration is _______________ to the mass of the object.
double, double
If you double the mass, you ______ the force. If you double the acceleration, you _____ the force.
quadruples
Doubling the mass and the acceleration ________ the force.
Newton’s second law
basically means that the force of an object comes from its mass and its acceleration.
Newtons = mass(kg) x acceleration(m/s²)
Force is measured in?
Mass
is the quantity of matter in an object.
Mass
Is a measure of the inertia or “laziness” that an object exibits in response to any effort made to start, stop, or otherwise change the object’s state of motion
Weight
Is the force of gravity on an object
Mass x acceleration due to gravity
 Weight is equal to?
Equilibrium
Things that are in balance with one another illustrate
Mechanical equilibrium
are stable, without changes of motion.
Mechanical equilibrium
is a state wherein no physical changes occur. Whenever the net force on an object is zero, the object is in
equilibrium law
Mechanical equilibrium is a state wherein no physical changes occur. Whenever the net force on an object is zero, the object is in Mechanical equilibrium - this is known as the ______________________
Sum of F = 0
what is the equation for mechanical equilibrium
resultant
To find the force necessary to put something in equilibrium, first find the
equilibriant force
The force necessary to put something in equilibrium is called the
equal but opposite
The equilibrant force is ___________ to the resultant.
For every action there is an equal and opposite reaction
Newton’s Third Law of Motion
Newton’s Third Law
describes the relationship between two forces in an interaction.
Action and reaction
What are the two forces in play when it comes to Newton’s Third Law of Motion
equal in strength and opposite in direction
Action and reaction forces are?
