WebKinetic energy is the capability of an object in motion to do work. The formula for the kinetic energy of an object is given by K = 1 2 m v → 2. The work done on an object is the change in kinetic energy. The work of each force can be found by taking the scalar product of the force vector and the displacement vector. WebThis is a common misconception, remember that the angle theta in W = FDcos (theta), is equal to the angle BETWEEN the force vector and the distance vector. Since the distance vector is facing the complete opposite direction of the force vector, then the angle between them will be 180 degrees.
