WORK, ENERGY AND POWER. A dot B) is defined as A.B = A B cos θ. (6.1a) where θ is the angle between the two vectors as shown in Fig. 6.1(a). Since A, B and cos θ are scalars, the dot product of A and B is a scalar quantity. Each vector, A and B, has a direction but their scalar product does not have a direction.

This video explains the work energy theorem and discusses how work done on an object increases the object’s KE.
20 Σεπ 2021 · Work–Energy Theorem According to the work–energy theorem, the work done by a force on a moving body is equal to the increase in its kinetic energy. W = ½ mv 2 - ½ mu 2 = k f - k i
This establishes a relation between work and kinetic energy, which is called the ``Work-Energy Theorem.”. It is expressed as: W = ΔK. Where, W = work done in joules (J), and. ΔK = change in kinetic energy of the object. It is a known fact that we all require Energy in order to Work.
