Kinetic energy is energy in motion.
From the seventh step of the stairs I dropped the hammer. (You can't see it but it's there!) When we calculated the potential energy (PE), we calculated the max potential energy. That means that 12.7155 was the total energy of the object and the kinetic energy (KE) was equal to zero. The max kinetic energy is how fast the object is going right when it hits the ground. |
Load bearing walls are walls of a building/house that carry the weight of other things inside the structure. Without these walls, some components would not be able to be there. One of the obvious ones is the walls holding up the loft, as you can see to the right. Without these three walls the loft would not be able to lean on them. |
