Understanding total energy in Simple Harmonic Motion (SHM) can be hard for 11th-grade students. There are two main types of energy we need to think about: kinetic energy (KE) and potential energy (PE).
The tricky part is seeing how these energies switch back and forth while the total energy stays the same.
The formula for kinetic energy is [ KE = \frac{1}{2} mv^2 ] Here, (m) is the mass and (v) is the speed.
At the furthest points (called maximum displacement or amplitude), the kinetic energy is zero.
The formula for potential energy is [ PE = \frac{1}{2} kx^2 ] In this equation, (k) is the spring constant, and (x) is how far the object is from the middle point (equilibrium).
At the middle point (equilibrium position), the potential energy is zero.
Many students find it confusing that at the farthest positions, all the energy is potential energy, while in the middle, all the energy is kinetic.
To make this easier to understand, we can use graphs. By plotting kinetic and potential energy against displacement, we can visually see how the energies change.
Doing experiments with springs can also help. When you can see and feel how energy works, it makes it much easier to understand energy conservation in motion!
