five forces competition

Force - A force is often defined as a "push" or a "pull". There is nothing untrue with this statement, but does not really tell you much about a force. Instead of defining force, it substitutes an antonym. A physicist prefers to define a force in te..

Any chemical substance which has a molecular structure that closely resembles a substrate, can reduce or inhibit the activity of an enzyme. Such an inhibitor is called competitive inhibitor. This situation is comparable to a lock jammed by a key almost similar to the original one. fi..

When two wet glass plates are pressed together, they cannot be separated easily. This is because of the force of attraction existing between the atoms and molecules, and are electrical in origin. As the two isolated Hydrogen atoms approach each other, the nucleus of one atom attracts the ..

Lorentz Force - The force experienced by a charged particle moving in space where both electric and magnetic field exist is called lorentz force. The lorentz force is therefore the vector sum of force due to electric field and the force du..

Force of Gravitation - What do you observe when you drop a stone from a height? The stone which was initially at rest starts moving towards the ground and attains a maximum speed just before it touches the ground. Is the stone moving with a constant speed? No, it is not moving with unifor..

[ sin (A - B) = sin A cos B - cos A sin B] It is clear from the figure that, Here, d is the perpendicular distance of the line of action of the force from the origin O. This is known as the lever arm of the force about the origin ..

Let us consider two situations Suppose a block of mass 'm' rests on a rough horizontal table. It is dragged horizontally towards right through a distance 'l', and back to its initial position. Let ' m ' be the coefficient of friction between the block and the table. Let us calculate the work done b..

The figures show a block of wood on a table. When the block is pulled at point A, it begins to move towards the left and if the block is pulled at the point B it moves towards the right. Example of Balanced Forces In a game of tug of war when both the teams pull the rope with equal and op..
