61Net force — For novel series created by Tom Clancy and Steve Pieczenik, see Tom Clancy s Net Force. In physics, net force is the total force acting on an object. It is calculated by vector addition of all forces that are actually acting on that object. Net… …
62Zero Moment Point — is a concept related with dynamics and control of legged locomotion, e.g., for humanoid robots. It specifies the point with respect to which dynamic reaction force at the contact of the foot with the ground does not produce any moment, i.e. the… …
63Conatus — This article is about a term in philosophy. For the Zola Jesus album, see Conatus (album). For the species of fish, see Platycephalus. Conatus (Latin for effort; endeavor; impulse, inclination, tendency; undertaking; striving) is a term used in… …
64Centrifugal force (rotating reference frame) — This article is about the fictitious force related to rotating reference frames. For other uses, see Centrifugal force. Classical mechanics …
65Second moment of area — The second moment of area, also known as the area moment of inertia or second moment of inertia, is a property of a shape that is used to predict its resistance to bending and deflection which are directly proportional. This is why beams with… …
66Special relativity — (SR) (also known as the special theory of relativity or STR) is the physical theory of measurement in inertial frames of reference proposed in 1905 by Albert Einstein (after considerable contributions of Hendrik Lorentz and Henri Poincaré) in the …
67Torque — For other uses, see Torque (disambiguation). Classical mechanics Newton s Second Law …
68Centripetal force — Not to be confused with Centrifugal force. Classical mechanics Newton s Second Law …
69Callisto (moon) — Callisto View of the heavily cratered terrain of Callisto s anti Jovian hemisphere obtained in 2001 by NASA s Galileo spacecraft. The large impact structure Asgard is on the limb at upper right. The prominent rayed crater below and just right of… …
70Flight dynamics — is the science of air and space vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle s center of mass, known as pitch , roll and yaw… …
