Phet Forces Friction And Motion Answer Key
In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and as explained by Archimedes' principle is equivalent to the weight of the fluid that would otherwise occupy the submerged volume of the object, i.
In this case, the string makes a constant angle with the vertical. The bob of pendulum describes a horizontal circle and the string describes a cone. Expression for Period of Conical Pendulum:. The time taken by the bob of a conical pendulum to complete one horizontal circle is called the time period of the conical pendulum. Expression for Tension in the String of Conical Pendulum:.

Most curricular materials in TeachEngineering are hierarchically organized; i. Some activities or lessons, however, were developed to stand alone, and hence, they might not conform to this strict hierarchy.

In physics , tension is described as the pulling force transmitted axially by the means of a string, a cable, chain, or similar one-dimensional continuous object, or by each end of a rod, truss member, or similar three-dimensional object; tension might also be described as the action-reaction pair of forces acting at each end of said elements. Tension could be the opposite of compression. At the atomic level, when atoms or molecules are pulled apart from each other and gain potential energy with a restoring force still existing, the restoring force might create what is also called tension. In physics, tension, as a transmitted force, as an action-reaction pair of forces, or as a restoring force, may be a force and has the units of force measured in newtons or sometimes pounds-force.
Several problems with solutions and detailed explanations on systems with strings, pulleys and inclined planes are presented. Free body diagrams of forces, forces expressed by their components and Newton's laws are used to solve these problems. Problems involving forces of friction and tension of strings and ropes are also included. We apply Newton's second law for each block. Physics Problems with Solutions. Tension, String, Forces Problems with Solutions. Problem 1 A block of mass 5 Kg is suspended by a string to a ceiling and is at rest.
Equilibrium is a special case in mechanics where all the forces acting on a body equal zero. This type of problem pops up in many situations and is important in engineering and physics. This equilibrium example problem illustrates how to determine the different forces acting on a system of forces acting on a body in equilibrium. Example Problem: A block of weight w is suspended from a rope tied to two other ropes at point O. One rope is horizontally attached to a wall and the other is fastened to the ceiling. What are the tensions in each of the ropes?
