Basics
forces are interactions between substances where these are transferred
bosons
the weakest force with the longest range
gravitational field
Fields are ___________ when the field lines are closer together
stronger
the effect of the gravitational field caused by a car:
negligible
the study of the forces that cause motion
dynamics
electrons and quarks are examples of this category of subatomic particles
fermions
the force which holds protons together in the nucleus
strong nuclear force
gravitational field
the effect of a magnetic field on a charged particle
an object in motion stays in motion and an object at rest stays at rest unless acted on by an outside force
scalars have this quantity
magnitude
the force responsible for beta decay
weak nuclear force
a field caused by charged particles, or changing magnetic fields
electric fields
the effect of an electric field on a charged particle
change in speed and/or direction
Newton's 2nd Law
the acceleration of an object is proportional to the force acting upon the object and inversely proportional to the mass of the object; OR the force required to move an object is equal to the mass times the acceleration
vectors have this/these quantities
magnitude and direction
the force which holds atoms and molecules together, and which prevents two objects from merging
electromagnetic force
magnetic fields
the effect of a magnetic field on a non-charged particle
no change
Newton's 3rd Law
For every force, there is an equal and opposite force
the three things that the universe is made up of
forces, fields, wisdom/intelligence
protons, being positively charged, want to repel each other and the closer they are, the stronger the repulsion; the strong nuclear force must overcome this and hold them together
this object cancels out electrical fields by creating an equal and opposite electrical field
Faraday Cage
in any field, the disturbances caused by an object move how fast and in which direction?
speed of light in every direction
the force of weight is derived from which of Newton's laws? what is the equation used to find weight?
Fw = mg, derived from Newton's second law
