Uniformly Accelerated Motion
Motion of changing speed When a force of a certain size and direction acts on an object, the object moves at a constant rate of speed. These movements are easy to find around us. For example, … 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
Collision 2
This experiment is, You can experiment with heavy golf balls and light ping pong balls. Put a ping pong ball on top of the golf ball and drop it as it is. The golf ball hits … more
Clay Shooting
Parabolic motion Let’s think about the motion of throwing an object horizontally. There is no horizontal force when there is no air resistance, so there is no change in speed. This time, let’s consider a dropping. … 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
Principle of Satellite
How cannonball become an artificial satellite? a. Imagine that a cannonball falls in a parabolic curve. The trajectory the cannonball draws is actually part of an elliptical orbit centered around the Earth. The center of the … more
Constant Velocity
Constant motion Constant velocity motion refers to motion with constant velocity. When a force is applied to an object, the object’s velocity changes, so the sum of all the forces applied to the object in uniform … more
Slingshot Effect
Slingshot effect Suppose you throw an elastic ball to a moving train. And since the train’s mass is huge, let’s assume that the ball’s mass is negligible compared to the mass of the train. At this … more
Gravity Assist
Run Gravity Assisted Navigation-How to increase the speed of a spacecraft using the moon’s gravity A method of increasing speed using the celestial body’s gravity as the spacecraft moves around a moving object is called ‘Gravity … more
Motion Analysis (with Webcam)
How to use Click on the object (usually a ball) to track on the screen. The position of the object is tracked and displayed on the screen at regular intervals. You can adjust the number of … 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
