Free Fall Motion Analysis
Why do light and heavy objects fall at the same time? The change in speed due to gravity is the same for all objects because the force and inertia acting on an object are proportional to … more

Newton’s Cradle
Newton’s cradle Newton’s cradle consists of five iron balls, each hanging on two threads to prevent the ball from spinning. Originally Newton’s cradle was created to demonstrate Newton’s third law. If you collide a ball from … more
Moment of Inertia (3D)
● It’s a tube. The radius of the tube is outside: inside = 0.75: 1. There is no rolling friction. ● It’s a tube. The radius of the tube is outside: inside = 0.5: 1. There … more
Inertia Force of Elevator
Elevator and inertia Elevators are an excellent place to feel the inertia force. Consider the case of taking an elevator and trying to go up from the lower floor. When you press the button that goes … more
Seismometer and Inertia
Inertia When the bus starts suddenly, the body momentarily leans backward. On the other hand, when the bus stops, the body is leaned forward. This is due to the nature of the object to maintain its … more
A Spaceship without Deceleration Engine
The inertia of the rocket Since there is no friction in outer space, stopping a rocket’s engine in motion does not stop it immediately. When the rocket’s engine is stopped, the rocket continues to move forward … more
