inclined plane

The Inclined Plane - A heavy load may be raised more easily by pulling it up along a sloping surface than by lifting it vertically. For example, heavy barrels are often loaded into vans by passing two ropes round them and hauling them up an incline formed by two stout ..

A heavy load may be raised more easily by pulling it up along a sloping surface than by lifting it vertically. For example, heavy barrels are often loaded into vans by passing two ropes round them and hauling them up an incline formed by two stout planks held apart by iron rod..

The situation here is almost the same as the situation in the figure, just that the body here is sliding up instead of down, the friction acts downward. Component perpendicular to the surface Component parallel to the surface (Note that the body is being pulled with a constant velocit..

Consider a solid cylinder of mass M and radius R, rolling down a plane inclined at an angle with the horizontal. Let us assume that the cylinder rolls without slipping. The condition for rolling without slipping is that at each instant, the point of contact P (rather, the lin..

Formation of Image by a Plane Mirror - Ray Diagrams - The following rays are usually considered while constructing ray diagrams: A ray of light incident on a plane mirror at 90 degree gets reflected from the mirror along the same path. A ray of light falling on a plane..

Let MM and MM' be two plane mirrors inclined at an angle 120 o and O be the object placed in between these mirrors. In this case there will be only two images viz., O 1 and O 2..

If the velocity of an object increases then the object is said to be moving with positive acceleration...

Galileo Galilee (1564-1642), a great Italian scientist raised a number of questions about the action of forces on a body with respect to the motion of the body. He performed various experiments and answered those questions by studying the results of his experiments. Aristotle, a Greek philosop..

Galileo's Observation and Origin of Newtonian Mechanics - Aristotle and other medieval thinkers believed that the natural state of bodies is the state of rest. Galileo opposed this concept. Galileo observed that, when a ball was made to roll down an inclined plane, its speed inc..

The potential energy decreases linearly with decrease in height. On the other hand, the kinetic energy increases with decrease in height. The horizontal line represents the total mechanical energy. Let us now consider a body sliding down a smooth inclined plane. Consider a smoot..
