## 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 the object’s mass. The … 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 is no rolling friction. … 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 up, you suddenly feel … 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 current state of motion … 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 according to the law … more
