P2- Forces Flashcards
Distance=
speed x time
what unit is speed in
m/s
what unit is distance in
m
what unit is time in
seconds (s)
acceleration=
change in velocity/time
final velocity^2 - initial velocity^2=
2 x acceleration x distance
what does a straight diagonally pointing line mean on a vt graph (south west to north east)
constant acceleration
what does a flat line mean on a vt graph
steady velocity
what does a curved line up mean on a vt graph
increasing acceleration
what does a straight diagonally pointing line mean on a dt graph (south west to north east)
steady speed
what does a flat line mean on a dt graph
stopped
what does a curved line up mean on a dt graph
accelerating
If forces are balanced the overall movement is…
nothing
if the thrust is more than the drag, the object is…
moving forward in the direction of thrust.
Newton’s first law
An object will remain stationary or at a constant velocity unless acted on by an external force
