Let the mass be m. Let the natural length of the spring be L. The defining equation of simple harmonic motion (SHM) is that the acceleration is proportional to, and acts in the opposite ...
Potential is the potential energy per unit at a certain location. For example in a electric field the electric potential energy depends on both the location of the charge in the field and the charge we ar...
A Scalar quantity has magnitude, but not direction. For example Speed is a scalar quantity.A Vector quantity has both direction and magnitude. For exampl...
As this is an isolated system and a simple pendulum starting at rest, at maximum height, all the energy is in potential energy. The known equation for potential energy is simply mgh (mass x acceleration d...
First, we model the child as a single point particle. Then, we add in arrows representing vectors for the relevant forces: friction, weight and the contact force. We can also assume that the child h...
