an object at rest remains at rest and an object in motion maintains it's velocity unless it experiences an unbalanced force
What is Newton's First Law
100
an unbalanced force acting on an object equals the object's mass times it's acceleration
What is Newton's Second Law
100
for every action force, there is an equal and opposite reaction force
What is Newton's Third Law
100
the name for the fact that all objects attract each other
What is gravitational force (gravity)
100
Force is measured in these
What is Newtons
200
the tendency of an object to resist being moved, or if the object is moving to resist a change in speed or direction until a force acts on the object
What is inertia
200
the formula that comes from Newton's Second Law
What is Force=Mass*acceleration
200
a quantity defined as the product of the mass and velocity of an object
What is momentum
200
as this increases, gravitational force between two objects also increases
What is mass
200
this is changed when the time of momentum's change is increased or decreased
What is impact force
300
this type of car seat distributes the force that infants may undergo when in a car accident
What is a rear or backwards facing car seat
300
this will decrease when the same force is applied to a larger mass
What is acceleration
300
the term for when the total amount of momentum in an isolated system stays the same
What is momentum is conserved
300
the motion of an object when only the force of gravity is acting on that object
What is free fall
300
when an object is doing this, it is constantly experiencing free fall, and can experience it indefinitely
What is orbiting
400
these prevent your inertia from letting you smash into objects around you because of a force, in this case, in a car
What is safety features (seat belts, airbags, crumple zones, etc)
400
an equation representation that the acceleration of an object is proportional to the net force on the object, and inversely proportional to the object's mass
What is acceleration=force/mass
400
the momentum equation
What is p=m*v
400
when an object is moving through Earth's atmosphere, and they stop accelerating because the force of gravity is balanced out by the force of air resistance
What is terminal velocity
400
this is the only place that free fall can really take place, object falling in Earth's atmosphere cannot experience free fall because they are not in this
What is in a vaccum
500
when an object has less of this, it has less inertia. if it has more of this, it has more inertia.
What is mass
500
the unit described as kg*m/s^2
What is Newtons
500
the reason why every force pair can still have unbalanced forces, and result in some sort of movement
What is: force pairs do not act on the same object
500
the equation for gravity
What is F=G*(m,1*m,2/d^2)
500
the curved path that an object follows when thrown, launched or otherwise projected near the surface of earth
