What do you understand by the displacement of a body is 50 m towards east? The displacement of a body 40 m towards east means –

The weight of a body is not a fixed property like its mass; instead, it is a measure of the gravitational force acting upon it. Because weight is calculated by the formula W = mg, where m is mass and g is the acceleration due to gravity, any change in the value of g directly … Read more

The universal force of attraction acting between any two bodies due to their masses is known as their gravitational force. So earth can attract with gravitational force any object. But that object too attracts the earth with the same gravitational force.

The poles are closer to the center of the Earth due to the equatorial bulge, which strengthens gravitation at the poles and weakens it at the equator. The equatorial bulge modifies how the Earth gravitates. This is why the value of g is maximum in the polar regions. Value of Trees Paragraph 1200 WordsHow to … Read more

A piece of stone and a piece of paper are dropped from the same height, it is seem that the stone reaches the ground first. Since the acceleration due to gravity does not dropped on the mass of the body, the acceleration of the stone and that of the paper would be the same. So … Read more

Electric current flowing through a conductor creates a magnetic field around it. This phenomenon is known as the magnetic effect of electric current. The direction of the magnetic field can be determined using the Right-Hand Thumb Rule: point your thumb in the direction of the current flow, and your curled fingers will indicate the direction … Read more

Friction, a force that opposes motion, exists in two primary forms: static and sliding. Static friction is the force that prevents an object from starting to move, while sliding friction acts on an object already in motion. The key difference lies in the nature of the surface interactions.   When an object is stationary, the … Read more

Sound is produced by a school bell through a process called vibration. When the bell is struck by a clapper or hammer, it begins to vibrate back and forth. These vibrations create compressions and rarefactions in the surrounding air. Compressions are areas of high air pressure, while rarefactions are areas of low air pressure. These … Read more
