The Water Cycle Experiment

The water cycle or also known as the hydrological cycle is a state that describes how water moves continuously on Earth. Water cycle through different stages include: Evaporation, Condensation, precipitation and flow. Then go back to the evaporation stage. The whole cycle begins again and hence the name “water cycle”. Stages of the Water Cycle…

Inertial Experiments at Eggs

Preface Inertia or inertia is the tendency of all physical objects to resist changes to the state of motion. Numerically, this is represented by the mass of the object. The principle of inertia is one of the foundations of classical physics used to describe the motion of objects and the effect of force imposed on…
