Gravitational potential energy (GPE) is energy within an object with respect to its height. The equation of gpe is:
GPE = mgh
where: m = mass of object g = gravitational constant, 9.81 m/s^2 h = height
For a given gpe of 20 J, the height can be calculated as follows: *Remember to be consistent with units. Since Joule is derived from SI units, make sure to use SI units for the other variables
Prior to touching the bar magnet, the magnetic domains in the nail were pointing in random directions. When Taylor touched the nail to the bar magnet the magnetic fields of the magnetic domains aligned and it became a temporary magnet.
