-
inertia
(physics) the tendency of a body to maintain its state of rest or uniform motion unless acted upon by an external force
-
leverage, purchase
the mechanical advantage gained by being in a position to use a lever
-
sound
mechanical vibrations transmitted by an elastic medium
-
flight, trajectory
the path followed by an object moving through space
-
resistance
any mechanical force that tends to retard or oppose motion
-
friction, rubbing
the resistance encountered when one body is moved in contact with another
-
moment of inertia
the tendency of a body to resist angular acceleration
-
ultrasound
very high frequency sound; used in ultrasonography
-
ballistic trajectory, ballistics
the trajectory of an object in free flight
-
gravity-assist
(spaceflight) a trajectory that passes close to a planetary body in order to gain energy from its gravitational field
-
acoustic impedance, acoustic reactance, acoustic resistance
opposition to the flow of sound through a surface; acoustic resistance is the real component of acoustic impedance and acoustic reactance is the imaginary component
-
drag, retarding force
the phenomenon of resistance to motion through a fluid
