Kinetic energy is the energy of motion. An object possesses kinetic energy when it is moving. The kinetic energy (KE) of an object is given by the equation:

In this guide, we've explored the concepts of work, energy, and efficiency in the context of physics. We've also applied these concepts to Aktiviti 13 in the Buku Teks Fizik Tingkatan 4 KSSM. By understanding these concepts, students can develop a deeper appreciation for the relationships between force, displacement, energy, and efficiency.

W = F × s = 20 N × 3 m = 60 J

GPE = m × g × h

A 50 N force is applied to a block, causing it to move 2 m to the right. Calculate the work done on the block.

W = F × s = 50 N × 2 m = 100 J

Energy is the ability to do work. There are two main types of energy: kinetic energy and potential energy.
