motion forces and energy

Is Newton's third law of motion applicable to gravitational force? Yes it is. Let us now see how Newton's third law of motion is applicable to the gravitational force existing between the various objects in the univers..

whenever a force is acting on an object, it produces acceleration in it. The gravitational force of attraction produces acceleration both in the Earth and in the ston..

Energy is a number that we associate with a system of one or more objects. If a force acts on one of the objects, making it move, then the number changes. After countless experiments, scientists and engineers realised that if the scheme by which we assign these energy..

Flowing or moving air is called wind. By the virtue of this motion, the wind possesses kinetic energy. A windmill is used to make practical use of wind energy. The force of the wind rotates the blades of the windmill. Wind should flow continuously with certa..

In real life an object which is moving over a horizontal surface does not continue with constant velocity when the accelerating force is removed. Instead the object slows down and eventually stops. The deceleration is caused by a frictional force between the object and the surfa..

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 ..

Forces Acting on the Bob of a Simple Pendulum - The bob of a simple pendulum is attached to a string which pulls the bob along its lengt..
