Then, calculate the efficiency:
KE = ½ × m × v^2
In this guide, we will explore the concept of work, energy, and efficiency in the context of physics. Specifically, we will focus on Aktiviti 13 in the Buku Teks Fizik Tingkatan 4 KSSM (Kurikulum Standard Sekolah Menengah) textbook. This activity aims to help students understand the relationship between force, displacement, and work done, as well as the concepts of kinetic energy, potential energy, and efficiency. Then, calculate the efficiency: KE = ½ ×
A 5 kg object is moving at a velocity of 2 m/s. Calculate its kinetic energy. A 5 kg object is moving at a velocity of 2 m/s
Efficiency = (Work done / Energy input) × 100% where m is the mass of the object and v is its velocity
where F is the force applied and s is the displacement of the object.
where m is the mass of the object and v is its velocity.
