get falling objects

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..

The objects which move towards the Earth due to force of gravity are called freely falling objects..

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 which pull..

In a game, a target is moving randomly on a vertical screen of length 8 m and height 9 m. A light source placed at 2 m in front of the board can be turned on with a switch. If the target is found with in the lighted portion of the screen a prize is won. Light is passed through a circle of 2 cm diam..

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 sticking some..

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..

When an object is placed in front of a concave mirror, light rays from the object fall on the mirror and get reflecte..

When colored light is incident on a white object it does not absorb any color and the light falling on it is reflected. If colored light is incident on a colored object it absorbs the light and the object appears black as no color is reflecte..

It is a process by which an exact image of any object can be made on a print out paper. This process is done with the help of light. Photography involves many steps. A film is prepared in dark and is fitted into camera. The image of any object falls on the film and a l..
