how to get falling objects

To understand how the resistance offered by air affects the rate of fall of freely falling objects, let us consider the following experiment. Drop a pebble and a piece of paper simultaneously from the same height. The pebble will hit the ground first. Now re..

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..

Falling Objects and Acceleration due to Gravity - 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 st..

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..

The Objective Function is a linear function of variables which is to be optimised i.e., maximised or minimised. e.g., profit function, cost function etc. The objective function may be expressed as a linear expressio..
