... Work W is energy transferred to or from an object by means of a force acting on the object. If the object is accelerated by applying a force, its kinetic energy K increases. Energy transferred to the object is positive work +W. If you decelerate the object by applying a force, you decrease its ...

Newton`s Second Law
... A 10 kg object is subject to a net force of 25 N. What is the acceleration of the object in m/s2? The second law says a = F/m. Therefore a = 25 N /10 kg = 2.5 m/s2 If the object starts at rest, then how long will it be before its velocity is 25 m/s? You know that v = v0 + at and v0= 0. Rearranging g ...

An important observation is that in both cases (sum of forces is zero or sum of forces is orthogonal to direction of motion) the speed of an object remains constant and thus any function of speed (i.e. magnitude of velocity) would not ch ...
