Merit Formula: Typically, the aggregate is calculated as: (AFNS × 50%) + (FSc × 40%) + (Matric × 10%). However, it may have changes for merit calculation formula and admission criteria. Please confirm the official criteria from the offical website.

1. The work-energy theorem states that the net work done on an object equals the change in its:
2. Power is defined as the rate of doing work. Its SI unit is:
3. If a force F moves an object with velocity v, the instantaneous power is:
4. A force of 10 N moves a body 5 m in the direction of the force. The work done is:
5. A mass of 2 kg is lifted to a height of 3 m. The work done against gravity is (g=10 m/s²):
6. A body of mass 5 kg is moving with a speed of 4 m/s. Its kinetic energy is:
7. If the speed of a body is doubled, its kinetic energy becomes:
8. If the mass of a body is doubled and speed is halved, the kinetic energy becomes:
9. A 1000 kg car accelerates from 0 to 20 m/s. The work done by the engine (assuming no losses) is:
10. The total mechanical energy of a system is the sum of its kinetic and potential energies. In the absence of non-conservative forces, this total energy is:
