Physics flash cards
system-✔✔the collection of objects that are of interest
closed system-✔✔a system in which masses do not enter or leave.
Isolated system-✔✔a system in which no net external forces act on the
object within it.
momentum-✔✔the quantity of momentum. momentum is the product of
mass and velocity, and because velocity is a vector, mass is also a vector
-✔✔=elapsed time- the definition of acceleration/change in time
-✔✔the change in momentum
Fnet-✔✔the net external forcer
Gravitational force (Fg)-✔✔Attractive force between two objects with
mass.
Gravitational field(g)-✔✔a model explaining the influence object extends to
produce a force on other objects.
Fg=G m1/m2 r^2-✔✔fg is gravitational force, G is the gravitational
constant, m1 and m2 are point masses, r is the distance.
g=Fg/m2=Gm1/r2-✔✔g is the gravitational field strength
Resistance forces that can cause an
object to stop.= friction, air resistance, gravitation.-✔✔friction, air
resistance, gravitation
D=r/t is the scalar version of?-✔✔v= s/t
