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

Inertia

Inertia

Run 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 … more

Constant Velocity

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

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

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

Addition of Force

Addition of Force 2

Three elements of force When a force acts on an object, the object’s motion varies depending on the Three elements of force. That is the magnitude, direction, and point of action. Therefore, when displaying a force, … more
