Fundamental Forces
Newton's Laws
Gravity
Potporri
Force
100
holds the protons and neutrons together in atomic nuclei
What is the strong nuclear force?
100
Objects at rest tend to remain at rest and objects in motion tend to remain in motion unless acted upon by an outside force.
What is Newton's 1st Law?
100
gravity is directly related to this
What is mass?
100
the equation is mass times veocity
What is momentum?
100
a push or a pull on a system
What is force?
200
attractive and repulsive forces related to moving and unmoving charges
What is electromagnetic force?
200
force is equal to mass times acceleration
What is Newton's 2nd Law
200
as this increases gravity decreases
What is distance?
200
between a flat piece of paper and a crumpled piece of paper, this one will fall at a slower velocity
What is the flat piece of paper?
200
the SI unit of force
What is the newton (N)?
300
attracts at distances smaller than the radius of a proton
What is the weak nuclear force?
300
for every action there is an equal yet opposite reaction
What is Newton's 3rd Law?
300
objects that are falling due to gravity alone are said to be in this
What is free fall?
300
a parachute works because of this principle
What is drag or air resistance?
300
because a force pushes or pulls with a ceratin magnitude in a certain direction it is called this
What is a vector?
400
the weakest of all forces although it can act over intergalactic distances
What is gravitational force?
400
an example of this law would be jet engines and rockets
What is Newton's 3rd law?
400
this is the highest velocity at which an object can fall
What is terminal velocity?
400
this property of matter causes objects to resist a change in motion
What is inertia?
500
responsible for holding the nucleus of an atom together
What is the strong nuclear force?
500
We need seatbelts because of this
What is Newton's 1st law?
500
this affects the speed at which objects can fall and applies mostly to bulky, low mass objects
What is drag or air resistance?
500
when riding up on an elevator your weight will do this
What is increase?
