what causes objects to fall

We know that whenever an object is dropped from a height, it falls towards the Earth. Similarly, when an object is projected vertically upwards, it goes up but after attaining a certain height, it starts falling down. It is the force of gravitation whic..

Aristotle, the great ancient philosopher performed some experiments to study the speed of freely falling objects. He observed that when two bodies of different masses were dropped simultaneously from the same height, the heavier object reached the Earth's surface earli..

Shortening of the eyeball, that is, the eyeball becomes smaller Increase in focal length of the eye lens Let us now see how this defect is rectified. A long sighted eye forms image of a nearby object behind the retina. Thus, long sightedness is due to the decreased converging power..

Kidney failure is caused due to many reasons: (a) Tubular injury (b) Infection (c) Bacterial toxins (d) Inflammation of glomeruli (e) Arterial or venous obstruction (f) Fluid and electrolyte depletion (g) Intrarenal precipitation of calcium and urates. (h) Drug reaction (i) Haemorrh..

1. The parents of these students do not place much importance on education. At the least provocation, they take the children out of school. Girl students are especially vulnerable. For them the household chores - carrying water, looking after siblings and marriage are considered more important. 2...

Cause of Periodicity of Elements - The modern periodic table is based on the electronic configuration of the elements. The properties of an element are determined largely by the electrons in its outermost or valence shell. Valence electrons interact with other atoms and take part in all c..

We can conclude that the object with a broad base as in figure (b) is more stable than with a narrow base as in figure (a). Experiment 2: Take a narrow hollow light cylinder and place it on the table. Give it a slight push and see what happens. Repeat the experiment by sti..

A real object can rotate as it moves. For example, a cricket ball may be spinning while it is moving, as a whole, in a trajectory. Also, a body may vibrate as it moves, for example, a falling water droplet. These complications can be avoided by considering the motion of a very s..
