Minimal force required for the lever

2023-12-102020-08-25

Lever A lever is a tool that transmits force using a rod. With a lever, you can work with it having little force. The length of the lever can adjust the minimum force required to move the lever. Work at … more

‘Work’ in science

2023-12-102020-08-14

‘Work’ in science ‘Work’ in science and ‘work’ in everyday life is a little different. In science, ‘work’ is to apply a force to an object and move it in the force’s direction. In the following cases, It is said … more

In a potential energy measurement experiment, why should an object be lifted slowly at a constant velocity?

2023-12-092020-05-20

In a potential energy measurement experiment, why should an object be lifted slowly at a constant velocity? When we apply a force to an object and move it in the direction of the force, we say that we have done … more

Conservation of Mechanical Energy in Rollercoaster

2024-08-192020-05-14

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

The principle of riding a swing

2023-12-112020-03-15

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

What is the fastest at the moment of hitting the ground? (Terminal Velocity)

2023-12-112019-08-11

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
