Science Flashcards
action-reaction pair
two forces that act on opposite objects
action force
the forces the 1st object exserts on the 2
reaction force
the force the 2nd object exerts on the 1st
force
(F) push or pull
counterforce
the reaction force
what is momentum defined as
Momentum is defined as inertia in motion
what is the symbol for momentum
(P)
mass
(M) any objects that has stuff that makes it up
vlocity
(v) Speed with direction
magnitude
number
vector
a variable with both number and direction
Inertia
an object reaction to change its motion
momentum
(P) inertia in motion
what is momentum equation
P=MXV
what is velocity equation
V=p/m
what is mass eqation
M=p/v
how do you change an objects motion
apply a force
what is the impulse equation
f*T=P
what are two ways in witch an object does change
either mass and velocity can change
assuming the mass of an object does not change what would case its momentum to change
velocity change in motion.
impulse
applying force to case a change in motion
change in momentum
change in motion
impsct time
(T) amount of time a force is applied for
elastic collision
bounce collision
