Efficiency is a measure of how much of the input energy is converted into useful work. It is calculated using the equation:
GPE = m × g × h
Efficiency = (Work done / Energy input) × 100% Efficiency is a measure of how much of
A 5 kg object is lifted to a height of 2 m above the ground. Calculate its gravitational potential energy. In this guide, we've explored the concepts of
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. GPE = m × g × h = 5 kg × 9
GPE = m × g × h = 5 kg × 9.8 m/s^2 × 2 m = 98 J
Efficiency = (Work done / Energy input) × 100% = (980 J / 2000 J) × 100% = 49%
