AP Physics 1: Dynamics Cards
Atwood machine - ANSwhen two blocks are connected by a cord that passes over a frictionless
pulley, a = g(-m1 + m2) / (m1 + m2)
centrifugal force - ANSnot a real force - just your inertia
centripetal acceleration - ANSacceleration of a rotating object, directed towards the center of
rotation
centripetal force - ANSthe force that causes circular motion
Dynamic Equilibrium - ANSobjects moving at constant speed in a straight-line path, constant
velocity, acceleration zero
Equation for Newton's 2nd Law - ANSNet force = (mass)(acceleration)
Equation for weight - ANSFg (weight) = m*g
examples of centripetal forces - ANStension, gravity, friction
Force - ANSa push or a pull, in Newtons, a vector
Free Body Diagram - ANShow forces are represented on an object
Friction Force - ANSthe force resisting motion (always in opposite direction), resistance force
Friction will always act in the direction.... - ANSopposing motion
Gravitational Force - ANSa pull that is directed toward the larger body, pulls an object toward
center of the Earth
How do you convert kg to N? - ANSmultiply mass by acceleration of gravity
If an object is at rest or moving at constant velocity, what is it's acceleration? - ANS0
If two masses are attached by a string, the tension on one side of the string is... - ANSequal and
opposite to the tension on the other side of the string
Kinetic or Sliding Friction - ANSresistance force between two surfaces already in motion, the
magnitude of this force is less than magnitude of static friction
