chapter 2: forces
fundamental forces
gravitational forces
electromagnetic forces
strong nuclear force
weak nuclear forces
fundamental/contact forces
normal forces
friction forces
tension
net force
when more than 1 forces acts on an object
subsequent motion determined by net force
vector sum of
all
the forces acting on an object
Newton's first law:
an object's velocity remains constant if and only if the net force acting on the object is zero.
inertia
resistances to
changes
in velocity
equilibrium
an object is in equilibrium when it has zero acceleration
Newton's 2nd law:
in an interaction between two objects, each object exerts an equal force on each other.
