In physics, the answer may surprise you! Today we will find out what really uses more energy. In this video, we explore a curious question in physics: does climbing a ladder or a ramp use the same amount of energy? We will understand the concept of work and gravitational energy and how the perception of effort varies between the two. Although the work performed is the same, climbing a ramp seems easier because the effort is distributed over a greater distance, while the ladder requires concentrated force with each step. Find out why the ramp seems less tiring and how physics and psychology influence our feeling of tiredness! 00:00 Introduction 00:30 The Problem 00:45 Analysis Using Energy 03:24 Analysis Using Forces and Vectors 09:55 Power and Accelerated Energy Expenditure 14:53 Summary ______________ ????
