What is the most common energy conversion?

What is the most common energy conversion? kinetic energy How does insulation stop unwanted energy transfers? Energy loss through walls can be reduced using cavity wall insulation. This involves blowing insulating material into the gap between the brick and the inside wall, which reduces the loss by air circulating inside the cavity, therefore reducing loss […]

Why is there no friction on ice?

Why is there no friction on ice? One of these theories is that friction causes the liquid layer of water to form on ice. Friction is the force that generates heat whenever two objects slide against each other. If you stand on ice without moving, no friction exists to generate heat, yet the ice is […]
