Conservation of Mechanical Energy If you look at the roller coasters, you can find something interesting. That’s right. There is no engine on the roller coaster. When we lift the roller coaster to the highest point, then the roller coaster … more
Kids have the know-how, but they can’t tell the principal. “How can you go so high?” Some principles are difficult to describe in words in the world, even if everyone knows. I think one of them is how to ride … more
Mechanical energy Mechanical energy is the sum of potential and kinetic energy. Mechanical energy = potential energy + kinetic energy Em = EP + EK Mechanical energy conservation Without friction, the sum of an object’s initial mechanical energy is equal … more
Kinetic energy All moving objects have kinetic energy. The kinetic energy Ek of an object with a mass of ‘m’ and a velocity of ‘v’ can be calculated as follows. \[E_{ k }=\frac { 1 }{ 2 } m{ v … more
