problems involving equilibrium in physics

This is derived from the Greek word 'dynamis', meaning power. Dynamics involves the study of the cause of motion, which is force. When we relate motion of an object to the forces associated with it and to the properties of the moving objects, we are dealing with dynamics. In this chapter..

.e., a to and fro motion. A given point in the path is crossed by the body in opposite directions at regular intervals. This is called oscillatory motion. All oscillatory motions are periodic but not all periodic motions are oscillatory. On observing an oscillating system, like a loaded spring, one..

Let the burner lie on its side as in figure below. Push it slightly and see what happens. On further pushing, the C.G. neither gets raised nor lowered. The burner just rolls maintaining its center of gravity at the same level. Objects like cylinders and cones lying on their side roll because they ..

What makes a body stable? An object is said to be stable if it is steady and well balanced so that when it is pushed slightly it does not topple or fall off easily. Let us try to do a simple experiment or derive the conditions for stability. Experiment 1: Stick three pins close together to the..

When two substances at different temperatures are brought together, heat energy flows from a substance at higher temperature to a substance at lower temperature. The heat flow continues till their temperatures are equalized. At this stage, the substances are said to be in thermal equilibrium..

Place the burner upside down as shown in figure below. A slight push causes the C.G. to be lowered and the burner begins to fall to make the C.G. as low as possible [Figure (b) below)..

A rigid body is said to be in equilibrium if, both the linear and angular momentum of a rigid body have a constant value. For the equilibrium of a rigid body, the body need not be at rest. However, if it is at rest, it is called the static equilibrium..

The body should have a broad base. Center of gravity of the body should be as low as possible. Vertical line drawn from the center of gravity should fall within the base of suppo..
